Acorn World 94
8.2
Norwich Computer Services has a large stand (N║46) next door to the
theatre at Acorn World 94 (28th Ö 30th October at the Wembley Conference
Centre). I do hope you will come along and see us. There will be some
special offers on Archive subscriptions, so bring your unconverted
friends along and get them to sign up Ö the more subscribers we have,
the better we can make Archive. To that end, weæve given you a coloured
sticky badge that you can wear at the show so that people will know you
read Archive and they can ask what you think of it. (It should be
somewhere in the envelope!)
8.2
We hope that some of the Archive contributors will also be around so
that you can chat to them and you will be able to talk to the Editor,
too.

Making Archive Better Ö Part II
8.2
I was going to write up some more of the ideas from the questionnaires,
but there were so many of them!! As the pile of blue papers on my desk
grew and grew, the size of the task grew and I never actually got
started Ö you know how it is Ö but Iæll do my best for next month. Mind
you, to be fair to myself, I have been working on some exciting new
plans for the long-term future development of Archive which I hope to
tell you a bit about next month. Watch this space...

Happy reading,

Å  16-bit audio card Ö Expressive Software Projects have launched the
first stage of their 16-bit Minnie audio card for the Risc PC. Priced at
ú69.95 +VAT, the card provides output via the internal speaker or the
headphone socket on the Risc PC. The software provided with the package
can handle playback from a number of sources. Later this year, the
second half of the package, providing MIDI synthesizer and MPC support
for the PC Card will be available, at ú39.95 +VAT.
8.2
Å  A4 colour scanneráÖáIrlam Instruments have now added the Canon IX4015
A4 flatbed colour scanner to their range of scanners using their Proi-
Mage software. This is a 400 dpi scanner that interpolates to 1200 dpi
in greyscale, taking only 20 seconds for full colour A4 scan. This high
speed is possible because it uses a SCSI interface. The scanner and
software costs ú699 +VAT including the software and leads (ú765 through
Archive). If you donæt already have a SCSI interface, that would be
extra, e.g. a Morley uncached card at ú160 through Archive.
8.2
Å  Acorn AdvantageáÖáThis isnæt a product as such but Acornæs latest
marketing campaign. Never-the-less, it provides opportunities that
Archive subscribers might want to take up. It is a membership scheme,
designed to build a mutually beneficial partnership between Acorn,
school teachers and parents. The teachers start the process by
registering with Acorn as Advantage agents (although Iæm sure they wonæt
call them öagentsò!). This wonæt cost them anything but simply means
that whenever they buy Acorn equipment for their school, they clock up
öpointsò for the school. Parents can also help in this because if they
buy an Acorn computer (from a participating Acorn dealer such as NCS!),
they will be given points that they can allocate to a school of their
choice. The school can amass these points (a bit like the Tesco scheme)
and use them to öbuyò equipment from an educational resources catalogue
which Acorn provide to the school.
8.2
Once teachers are registered on this scheme, they can ask Acorn to send
them as many öconcerned parentò packs as they want and give them to all
the pupils to take home, thus encouraging parents to buy Acorn computers
and earn points for the school. If you are a teacher and want to join,
just ring the Advantage Helpline on 0181-673-5455 and ask for a teacher
pack. Teachers registered on the scheme also get personal benefits
including discounts on national events, training and conferences,
regular free reports on educational and IT issues, magazine
subscriptions and educational directories.
8.2
Basically, it seems to be a öno-loseò situation. Teachers gain by
getting free perks and free information, parents who buy Acorn computers
get a system that will allow their children to do educationally valid
tasks at home and, at the same time, help the school with points, so
they donæt lose anything, and schools gain by getting free educational
resources. Oh, and Acorn donæt lose either because people buy their
computers!
8.2
Å  Acorn Desktop Guide is aimed to fill the niche between tutorials and
manuals. The Norfolk Information Technology Team have produced this
booklet as a reference for new users first learning their way around the
desktop. 28 ring-bound cards cover basic use of the desktop, icons,
mouse, keyboard, discs and printing. The guide is available from Norfolk
Educational Press at ú6.95 all-inclusive (cheques made payable to
Norfolk County Council).
8.2
Å  Acorn Early Years pack Ö Acorn have launched a new computer pack for
the A3010 aimed at parents with primary age children. The Early Years
Pack consists of a 2Mb A3010 with no monitor so you can use whatever
screen you like Ö you can even use your existing TV for the absolute
minimum budget version. There is a range of software available with it
and the total price is ú499 inc VAT.
8.2
The software packs are:
8.2
Talking Start-Write (Icon Technology) Ö a fully-featured, although
simple to use, word-processing package. It uses outline fonts and allows
the incorporation of pictures into the text. It can also talk the words
as they are typed, providing reassurance that they have been typed
correctly.
8.2
Explore with Flossy the Frog (4Mation) Ö a graphical adventure where the
user is in control of what actually happens. The delightful pictures
encourage questions, and the different objects in the pictures all have
different effects and actions.
8.2
Mouse in Holland (4Mation) Ö In a similar vein to Flossy the Frog, it
allows the user to explore the life of Martin Mouse, who lives in a
windmill. With many scenes including the Dutch countryside, canalside
Amsterdam and an art gallery, as well as inside the windmill, the
graphics encourage the user in terms of an overall goal of finding
fruit, cheese and moles!
8.2
Doris the Dotty Dog (Sherston) Ö This is a talking story with still
pictures and animations. It can be used by a parent with a child who is
not yet reading or by a child on their own to develop their reading and
vocabulary Ö individual words may be spoken if they are not known.
8.2
Gemini (Cambridgeshire Software House) Ö This is a computer version of
pelmanism with many different card sets making it suitable either for
very young children who can recognise shapes with only a few cards, or
for older children who can identify more complex pictures.
8.2
Amazing Maths (Cambridgeshire Software House) Ö In this package you have
to find your way through a maze while being asked arithmetic problems by
the computer. The parent can set the difficulty of the questions asked,
both in terms of the numbers used and the operations (add, subtract,
multiply and divide) that are available. This can then be used to
reinforce mathematical skills from simple addition (as one stage on from
counting) to providing the whole range of numerical operations.
8.2
Paint Pot (Emerald Publishing) Ö By dipping into the paint pot, you can
learn how to use the !Paint program. The book (and accompanying disc) is
written so that it can either be used by a parent encouraging their
child, or by an older child who can read themselves. Simple examples of
many of the facilities of paint are given as drawings of real objects.
There is also a library of animals and sea creatures that can be used to
build a jungle scene or an undersea picture. Ideas for projects using
Paint are also provided Ö and this keeps children fascinated for hours,
with no risk of spilling poster paint on the settee!
8.2
Å  Acorn Publisher is a new subscription magazine for the Acorn world.
It will cover all aspects of publishing on Acorn computer systems,
including electronic publishing and multimedia. The aim will be to
promote the Acorn platform as a high quality professional system capable
of addressing a large proportion of the needs of professional publishers
and designers, as well as catering for a more popular user base. A
second aim will be to raise the standard of publishing based on Acorn
systems.
8.2
The new magazine will be A4 in size, printed on quality paper with full
colour cover and mixed colour/mono contents. The magazine is entirely
edited and produced on an Acorn Risc PC, and aims to be an example of
all that is possible on an Acorn system.
8.2
The magazine will be published every other month with the first issue
scheduled for publication on 10th October this year. Subscriptions are
ú24.95 in the UK, ú28.95 in Europe and ú32.95 elsewhere.

inclusive (no VAT) from Eastmond Publishing. A site licence costs ú180.
(It was reviewed in Archive 7.12 p77.)
8.2
Å  CartridgeMateáÖáHow would you like to have an inkjet cartridge
refilling system that just involves putting the cartridge in a box and
pressing a button Ö no plastic gloves, no ink spilt on the table, etc?
Well, if you have a printer that takes Hewlett-Packard 51626A high
capacity cartridges, you can Ö more or less. I havenæt tried the system
yet but it looks extremely simple and easy-to-use. The system plus two
38ml ink tanks costs ú36 through Archive and the extra 38ml tanks are
ú22 for a box of two.
8.2
Å  Clicker is a new piece of software from Crick Computing. It provides
an on-screen overlay keyboard, with facilities for speech in software.
The program displays a grid of configurable size on screen, in which can

word processor, for example, or provide a link to other grids for a
hierarchical structure. Cells can also contain function and editing
keys. Switch Clicker is a special access version of Clicker for users
who are unable to use a mouse, allowing switch users access to the RISC
OS desktop, and providing all the facilities of Clicker together with

8.2
Å  Impression upgrades Ö There has been some confusion over the cost of
upgrade paths between the various versions of Impression. We said in
this magazine (7.6 p9) that owners of Impression II could upgrade to
Style for ú29 +VAT through Computer Concepts. This is correct. Then we
reported that öwhen Impression Publisher is released, Impression Style
owners and Impression II owners will be able to upgrade for ú29 +VAT.ò
However, that meant that owners of Impression Style who had previously
owned Impression II could upgrade at that price. New purchasers of
Impression Style wanting to upgrade to Impression Publisher will have to
pay CC ú70 +VAT. In fact, the ú29 upgrade was an introductory offer and
it now costs ú49 +VAT to upgrade from II to Publisher. (There is also a
p&p charge of ú3.53 to add.)
8.2
(As a now very satisfied user of Impression Publisher, I can say that I
think it is worth every penny of the upgrade price Ö see page 18 for
details. Ed.)
8.2
(Editor then dons sales hat and says... We have found three copies of
Impression II in our stock room so if anyone wants Publisher on the
cheap, they can buy Impression II at a special price of ú60 and then get
it upgraded by CC. The total cost is then just over ú130 Ö a real
bargain! Ed.)
8.2
Å  InTouch is a concept keyboard program aimed at the early stages of
childrenæs cognitive development. The package was designed originally

aspects that are appropriate to other phases of mainstream education.

colour/object/number recognition, matching and sequencing as well as a
scanning communication aid (using one or two switches) all of which can

Government Health Warning Ö Reading this could seriously affect your
spiritual health.
8.2
Did any of you see that TV program recently in which the biologist,
Richard Dawkins, talked about a world without religion? Or perhaps you
have read his books öThe Blind Watchmakerò and öThe Selfish Geneò? We no
longer need to invent a thing called öGodò to explain away the bits we
donæt understand Ö a scientific view of life explains everything. We are
all just a product of our genes and the way things have evolved can be
described in purely mechanistic terms. But, as a good scientist, Richard
Dawkins would never (I hope) say that he had öprovedò that God doesnæt
exist, but rather that he has a theory (call it ÉTheory Aæ) which is a
perfectly plausible explanation of the observable facts.
8.2
OK, thatæs fine but I have a different theory (call it Theory B) which
is, I believe, an equally plausible explanation of the observable facts.
The bible says that...
8.2
Sorry, but I had to stop. When I mentioned the bible, I felt the
shutters go down! What was your reaction? Was it öOh no, not that old-
fashioned, reactionary view again!ò or öWhy should I let the bible tell
me how to live my life?ò or öScience has disproved the bible, anyway.ò
or maybe it was öLook at all the evil that has been done by the church
over the years, using the bible as its authority!ò Those are some of the
reasons I have been given by readers over the months to explain why they
canæt accept Theory B.
8.2
Itæs funny you know, but some of the people who prefer Theory A are
amongst the most faithful readers of the God-slot. öIæm not a religious
person but I read your God-slot every month.ò Why is that, I wonder?
Well, according to Theory B itæs because we have a Father who created us
and therefore thereæs a socking great big hole in the life of anyone who
doesnæt have a loving relationship with God. What is more, we make a
mess of our human relationships, too, because of the insecurity created
by that lack of love.
8.2
öWhat a load of rubbish! How can anyone fall for such religious mish-
mash?!ò Hang on a minute! What happened to the careful scientific
approach to examining my Theory? Well, Iæll tell you what happened to
it. According to TheoryáB, you are suffering from a disease called
Éprideæ which affects a human beingæs judgement. öAre you trying to tell
me that for all the xxx years I have lived on this earth I have been
wrong in my view of God?ò Well, yes, possibly.
8.2
Tell me, are you open enough in your thinking to investigate a new (old)
Theory? öNo thanks, I donæt want to end up a religious nutcase like that
Paul Beverley.ò You see, you are at it again. Youære not approaching
this coldly and clinically and logically. Youære saying, öIæm not going
to look into this because I donæt like the implications. If I came to
believe in Theory B, Iæd be an object of ridicule in my family and at
work.ò
8.2
Are you prepared to examine the evidence for Theory B? Are you prepared
to face up to the implications that follow if you do come to the
conclusion that the evidence is very strong that, for example, Jesus did
rise from the dead? Well, I tell you, all over the UK, thousands of
people are looking into it by going on these Alpha courses, and
thousands of people are saying that their lives have been transformed by
God in a wonderful way. I have seen my own 49-year-old cousin change in
a most wonderful way just recently Ö he has such a peace and a new joy Ö
itæs just brilliant to see!
8.2
öHuh! Itæs getting worse! More religious mumbo-jumbo. They are being
brain-washed! Silly people! I wouldnæt fall for that.ò Well, all I can
say is that, if it is brain-washing, it must be very clever brain-
washing because the people becoming Christians are taking their friends
on the next course Ö and they are going along because they can see that
something has happened to their friend and they want to know what it is.
8.2
öThis is getting ridiculous! The God-slot is getting longer and longer.
Religion is taking over the Archive magazine that I have paid good money
for.ò Sorry about that but Iæll give you a pro-rata refund for the
missing technical information or a refund if you want to cancel your
subscription in disgust. But if Theory B IS correct then it is THE most
important thing for EVERYONE to find out about. Why not check it out Ö
youæve nothing to lose and everything to gain!

Acorn World 94
8.2
Acorn World 94 promises to be another impressive showcase for Acorn and
associated companies. Letæs hear first what Acorn are planning...
8.2
News from Acorn Computers
8.2
ÉA World of Opportunitiesæ is the theme of Acorn World É94, which takes
place at Wembley Exhibition Centre, London from October 28-30th. The
show has already attracted support from many leading companies and is
set to be the largest ever showcase for Acorn products and services
worldwide. The show will include a series of themed feature areas,
providing a glimpse of technological innovation in the interactive
media, publishing, education and home business sectors. These areas will
demonstrate the innovative synergy Acorn can provide between the home,
the classroom and the office.
8.2
Acorn Computers will be showing highly tuned Risc PCs, bringing new
levels of expandability and flexibility to the personal computer market.
Using production systems and some technology östraight from the labsò,
Acorn will give technically aware users examples of developments that
could be forthcoming in the next months and years. These illustrative
systems will give a pointer to the potential for Acorn computers and
show some of the options that could be developed.
8.2
As a central feature, on the main stand will be the all-time Acorn
örocket shipò Risc PC. This will be a revolutionary seven slice Risc PC
configured with a whole host of interesting add-on devices to show the
power and flexibility of the system.
8.2
Acorn will also preview a five processor adaptor card for Risc PCs that
allows up to five ARM processors to be fitted, in addition to a
heterogeneous standard second processor card.
8.2
The Acorn Risc PC card developed jointly by Acorn, Atomwide and Future
Technology Devices Inc will also be featured at the show. Some of these
will be configured with DX2 but DX4 chips will also be previewed. Acorn
will be running standard DOS, Windows and OS/2 operating systems and
software on these processors.
8.2
Operating system developments that will be shown will revolve around a
host of different applications. The current plans, should ensure that
the following are on view: OS/2 on the new PC cards, Unix native on Risc
PC, TAOS (a multi-processor operating system) on ARM processors. These
will all emphasise the broad range of options that the Risc PC can
deliver.

The Acorn enthusiasts will also have the opportunity to sign up for the
Acorn Enthusiastsæ Scheme. Competitions will be offered to encourage
people to join the scheme. There will be opportunities to win an ARM 700
processor card for your Risc PC, be one of the first owners of a 486
card for Risc PC and a choice of processors and a multiprocessor adapter
board to allow your Risc PC to carry several ARM processors. The
competitions will be based on a multiple choice question paper with a
tie breaker. Full details will be made available at the show.

From the Acorn family...
8.2
From our trawl around the Acorn-associated companies, the following
information about new products etc was gathered by Andrew Garrard. (Does
anyone fancy the job of going round all the stands at the show with the
list below checking which, if any, are öProducts Availableò and then
writing it up for the magazine? Itæs quite a big job but good fun at the
time. The hard slog is getting it all written up in time for the next
magazine which means getting the copy to me within 3-4 days of the end
of the show! Thanks. Ed.)

Å  Acorn, you cannot be serious!áÖáHow can Acorn computers be taken
seriously in the öreal worldò if they donæt have an implementation of
C++? And how can they succeed in tertiary education without being able
to run Unix? Come on, Acorn how can we recommend the RiscáPC to our
friends and colleague without some serious support?á Keith Parks,
Uxbridge.
8.2
Keith, youæll be pleased to hear that Acorn are going to be
demonstrating Unix on a RiscáPC at Acorn World 94. All we need then is
C++!! Ed.
8.2
Å  Apple were wrong!áÖáThe Advertising Standards Authority has finally
and fully upheld Acornæs complaints about some of Appleæs advertising
claims relating to the Power Mac. Acorn objected to statements like...
öApple is the first company to ship personal computers with RISC-based
microprocessors.ò (They were seven years out of date Ö the A310 in 1987
was actually the first.) Iæm sure that the deluge of complaints from
angry Archive subscribers that the ASA received was a helpful
contributory factor in righting this wrong Ö mind you, the adverts first
came out in March 1994, so Apple have had ample time to get their
(incorrect) message across before being told not to do so!
8.2
In case they try something else, letæs all have the ASA address to hand
so that we are quicker at responding next time Ö Advertising Standards

Å  öC books, pleaseò Ö In answer to last monthæs plea... In the course
of many years of C programming, a large number of books have passed
through my grubby hands, but few have stayed close to hand. Those I
would recommend, however, are:
8.2
Andrew Koenig, C Traps and Pitfalls (Addison-Wesley, ISBN 0-201-17928-8)
8.2
Koenigæs a hero of mine. One of Bellæs finest, he writes wonderful
columns on C++ in Joop and C++ Report these days. I look at his C Traps
and Pitfalls these days and think öcan I ever have not known that about
C?ò, but I remember the days when each page was a revelation Ö just like
his C++ writings today. Itæs pretty much a dictionary of oddities of the
C grammar.
8.2
Herbert Schildt, The Annotated ANSI C Standard (Osborne McGraw-Hill,
ISBN 0-07-881952-0)
8.2
The book is in a format where odd pages contain the ANSI standard, and
even pages contain Schildtæs comments. He says little of worth and makes
numerous mistakes. Far from clarifying the standard, he makes me wonder
if heæs actually read it. Having said that, I wouldnæt be without this
book. It costs much less than half the price of the ANSI standard, so I
can ignore Schildt and remember Iæm only a poor student. Beware of the
printing (like mine) where pages 131 and 132 are identical.
8.2
Donald Lewine, POSIX Programmeræs Guide (OæReilly & Associates, ISBN 0-
937175-73-0)
8.2
This book is probably the least relevant to the RISC OS programmer, but
if youære interested in C in a wider context (that of Posix Ö the
standard Unix API), this book is the best Iæve found. Its function
reference contains the entire ISO (or ANSI as was) C library, plus the
Posix functions (covering things like terminal handling, job control
etc). If you plan on writing for Unix, this bookæs pretty handy. Very
few errors that Iæve found, but there are sections where you wish heæd
gone deeper. The first few chapters are useless for anyone who considers
themselves a C programmer (the intended audience for the book).
8.2
P J Plauger, The Standard C Library
8.2
A book Iæm looking forward to reading is Plaugeræs book about how to
implement the functions in ISO Cæs library. I used to enjoy his column
in Computer Language, and expect this to be an excellent book.
8.2
For those looking to the future and C++ on their Risc PC...
8.2
Bjarne Stroustroup, The C++ Programming Language
8.2
Need I say more?
8.2
Bjarne Stroustroup, The Design and Evolution of C++
8.2
Buy it and read about language design from a master of the art.
8.2
Donæt accept any imitations: no-one writes better C++ books than Bjarne.

Å  GraphDraw Ö If any GraphDraw users are about to purchase a RiscáPC,
they are warned that the version on general release has a minor bug
which prevents it working on the RiscáPC. Send me a formatted disc and
return postage for a version which (I believe) does work without problem
on the RiscáPC (I do not yet have access to a RiscáPC, so can only
respond to users problems indirectly). Chris Johnson, 7, Lovedale Grove,
Balerno, Edinburgh, EH14 7DR.
8.2
Å  Publisher, an editoræs experience! Ö Having used Impression Publisher
for a few weeks now and produced one complete issue of Archive on it
(well, itæll be two by the time you read this!) I thought Iæd let you
know how Iæm getting on with it. Here are my impressions (sic) as they
came to me, historically.
8.2
Keyboard shortcuts Ö I think anyone upgrading from Impression II to
Publisher will find some degree of frustration over the different use of
keyboard shortcuts Ö especially <ctrl-A>. Although I knew to expect this
problem of different shortcuts, it came as bit of a shock to find that
so many of the style shortcuts I use regularly are unavailable now.
Apart from <f1> to <f4>, <f9> and <f10>, I used to have styles on <ctrl-
shift-f1> right through to <ctrl-shift-f10>, all of which are now
unavailable apart from <ctrl-shift-f4>. Bad news!
8.2
The worst of all is the lack of <ctrl-A> for deleting. I used to have my
left hand hovering over <ctrl>, <A> and <S>, then, with my right hand,
Iæd use the mouse to locate the cursor, perhaps double-click a word or
treble-click a line or double-click a word and then <adjust>-click to
make a selection and finally press <ctrl-A> to delete it.
8.2
My first attempt at a solution was using Keystroke to make <ctrl-Z> do a
<Copy>, i.e. delete to the right. Thatæs OK for deleting single
characters but as Publisher uses <ctrl-Z> to unselect a region, that
didnæt work for deleting a marked area so I now have to remember to use
<ctrl-X>.
8.2
Also, <ctrl-Z> working through Keystroke doesnæt respond very quickly,
so you canæt (easily) use it to delete, say, three consecutive
characters. Bring back <ctrl-A> Ö it was SO convenient. öYou canò, said
the man at CC. öJust define a style with no features and give it <ctrl-
A> as the shortcut and that will disable <ctrl-A> from selecting the
whole text.ò Nice idea, but I need to öselect all the textò on a regular
basis too, so unless thereæs some other easy way to do that, I canæt use
that technique Ö plus the fact that you have to install this phantom
style in every document.
8.2
I tell you, Iæm so hampered by the lack of <ctrl-A> as a delete that Iæm
thinking of gluing a new key on the LHS of my keyboard and wiring it up
to the delete key! Anyone got any other suggestions?
8.2
Crashes Ö As I reported last month, at first I had about three or more
crashes a day Ö öInternal Error at xxxxxò and then, when I tried to
continue, öError EL00ò. Just quitting and reloading didnæt seem to clear
it properly as it tended to crash again quite quickly. I took to using a
complete power-down, power-up. Then, when I pasted up last monthæs
magazine, I started about 6 a.m. and worked through until tea time Ö no
crashes. I started on it again at 9.00p.m. that night and worked through
until 1.30 a.m. (Itæs tough being an editor!) No crashes. Then, as I
tried to do almost the very last job of creating the contents list, it
crashed! Coincidence? Well, the way I create the contents list, involves
creating a new Impression document, and that was when it fell over.
Could it be that Publisher doesnæt like the default document that I
dragged over from Impression II? I sent it off to the CC laboratory for
analysis. CC say, öWe do not recommend that default documents are
carried over from previous versions of Impression...ò so Iæm busy
recreating my special master pages and porting across my special
styles.£
8.2
Impression loaderáÖáEach month, when I have finished the magazine, I
have to create the öWords Discò, i.e. I have to scrape out all the text
from the whole magazine and create an Edit file of it. Hitherto, I have
done it by going into the magazine directory, looking in the Chapter2
directory and taking out the file called öTextò. I drop this into an
Impression document and, having loaded the öLoadImpò loader, it
recognises the filetype and re-constructs all the text as one file. I
then just save the text without styles and bingo. Unfortunately, when I
tried this with Publisher, it crashed. CCæs verdict is that öthe LoadImp
module does not work with Style or Publisherò so I am going to have to
keep a copy of Impression II on my system just to use LoadImp each month
to create the magazine words disc!
8.2
Speed Ö I donæt do anything fancy in Impression Ö the magazine is all
fairly basic DTP stuff Ö but my first impression (sorry to use that word
again, but Wordworks canæt (or wonæt) find a suitable synonym) is that
Publisher is faster in general layout work. Certainly, the area where I
noticed a big difference in speed is in file-handling. I use huge
numbers of Impression files, so the single-file format is very much
faster when you come to opening directories full of documents.
Brilliant!
8.2
(One other drawback I find is that the new filetype icon is so dowdy, I
canæt easily find the files in a filer window or on my pinboard. The old
Impression öIò icon was much more distinctive and stood out clearly.
Anyone want to design me a new single-file Impression icon?)
8.2
Keystroke Ö Arrrgghhhh!!!! More than half the things I had come to rely
on in Keystroke donæt work! I tell you Ö it was like trying to work with
one hand tied behind my back. I knew that Keystroke had speeded things
up but I didnæt realise quite how much Ö just simple things like
keystrokes that do search and replace, changing double space into single
space or double CR into single CR. None of the search and replace items
worked and several of my editing speed-up tricks, like transposing
adjacent words, also failed me! Stuart sent me Keystroke version 3.06
and also warned me that Publisheræs use of the <alt> key means that a
number of things donæt work properly. Iæm hoping someone will offer to
start a Keystroke Column, so I wonæt go into the work-arounds here.
(Literally hundreds of Archive subscribers took up our special Keystroke
offer Ö so there is a huge audience for anyone prepared to start a
Keystroke Column!)
8.2
Crashes explained Ö Another source of crashes has just been identified
and reported to CC as it is actually a bug. I tried to use one of my
Keystrokes to put a comma at the end of the last word on one line but I
accidentally put it at the beginning of the first word on the next line,
i.e. after the space instead of in front of it. I placed the cursor in
front of the comma and attempted to use <shift-ctrl-Q> to switch the
space and the comma and the result was fatal Ö Publisher died completely
with no way of saving any un-saved file(s). Arrgh! This is entirely
repeatable and also occurs in Publisher Plus but not in Style Ö at least
not the version we have here. Actually, itæs nothing to do with it being
a comma Ö just trying to transpose the first character of one line with
the space at the end of the previous line.
8.2
Drag and drop text editingáÖáI discovered this by accident when the text
Émiraculouslyæ moved from place to place in the document I was editing.
If you havenæt discovered it yet, refer to the manual Ö it makes editing
quite a bit easier in many instances.
8.2
Overall, as I go on with Publisher, I am getting more and more confident
with it. I still get some nasty crashes if I try to load and edit old
files (especially 2.5Mb Archive magazine files!) but if I know to be
careful with those files, thatæs fine. If necessary, I can load them
into Impression 2.19 Ö which I keep on my Pinboard. Yes, Iæm glad I
finally plucked up courage to make the change. (Hmmm, since I wrote
that, Iæve been getting more crashes Ö seems to be mainly after I have
handled lots of different files and cut and pasted bits between files Ö
which, as a magazine editor, I have to do rather a lot!)á Ed.
8.2
Å  Publisher help Ö Help is at hand. We have had an offer from Keith
Parker to try to help with any problems that folk have with Publisher.
If you send your problems to Keith, he will work with Tony Tolver of T-J
Reproductions (well known for their Impression-based type-setting etc)
to try to find a solution. Keith Parker, 61 Frensham Close, Southall,
Middlesex, UB1 2QY.
8.2
Å  Publisher again Ö Chris Johnson writes: We have been experiencing a
number of problems with Publisher, particularly the network version,
which appears to crash much more regularly than the stand-alone version,
and also seems to lock up the network print spooler (and consequently
the fileserver) regularly as well. The problems appear when graphics are
in the document. The odd thing is that the same machine and the same
document gives different behaviour depending on whether the network or
the dongled stand-alone version is being run at the time. Has anyone had
similar problems or, better still, got a solution?
8.2
I also had the very odd experience of tidying up my hard disc 4,
including moving the location of !System, and then finding that
Publisher when next run gave the error message something like öthis copy
of publisher is corrupt Ö please reinstallò. Publisher was on hard disc
5, and I am convinced that there was no way that it could have been
corrupted. I had to go through the whole installation process again
before it was usable! I cannot believe that path names are öhard wiredò
into it when installed! (They are Ö for the benefit of OLE and also,
because there is some degree of software protection built in to the
installation method, I gather. Ed.) Chris Johnson, 7, Lovedale Grove,
Balerno, Edinburgh, EH14 7DR.
8.2
Å  Scientific software Ö Archive readers are reminded that I offered to
act as a collator for any type of scientific and mathematical software.
There are now two discs of applications, which can be obtained by
sending two formatted (800Kb) blank discs, together with return postage.
I should also be pleased to receive any software for inclusion on
further discs. I still feel there is a very distinct lack of cheap and
cheerful scientific software available for the Acorn RISC computers. If
there are programmers out there who have written useful scientific
routines, but are unsure about converting them to full blown
multitasking WIMP applications, then let me know. I may be able to help
to wrap them up in a WIMP shell. Chris Johnson, 7, Lovedale Grove,
Balerno, Edinburgh, EH14 7DR.
8.2
Å  Spreadsheet Column Ö Regular readers may have wondered what happened
to the spreadsheet column. The short answer is that all contributions
ödried upò once version 2 of Eureka was released. I have certainly found
that almost all the öfeaturesò of version 1 that were the subject of
much correspondence (quite heated at times) were addressed in one way or
another in version 2. Eureka still has its idiosyncrasies, and one or
two things I find infuriating, e.g. the total lack of any print preview
facility.á In spite of this, I find that it is on the whole a very good
piece of software.
8.2
I take this opportunity to remind readers that I am still ready to edit
a spreadsheet column, so if you have any comments, hints or tips, ideas,
suggestions, problems, or solutions to problems, connected with the use
of spreadsheets then drop me a line. My address is given below. If I
have sufficient response, then I will resurrect the column.
8.2
The only two communications I have received in the last few months
suggested that there should be a öhow to use spreadsheetsò series. I
would be willing to have a go at this, but would be interested to hear
from Archive members suggestions about what should be included, e.g.
should it start from absolute first principles, or should it be on more
advanced uses. It could be made part of a regular spreadsheet column, or
be completely independent.

Online Media Ö A World First?
8.2
This Acorn press release came into the Archive office the day before the
magazine was due to be finished so here it is, verbatim...
8.2
Online Media goes live with the worldæs first digital interactive
television trial in Cambridge.
8.2
In Cambridge today, Online Media will be Éswitching onæ what is believed
to be the worldæs first interactive television trial to be based on ATM
digital technology.
8.2
The trials are being launched by a consortium of Anglia Television, ATM
Ltd, Cambridge Cable and Online Media. The consortium, set up by
Cambridge Cable, is headed up by local firm, Online Media, also selected
to supply the intelligent, digital set-top boxes for the trial. The
technologies involved are Online Mediaæs set-top boxes, ATM Ltdæs
digital ATM (Asynchronous Transfer Mode) networking technology and
Cambridge Cableæs fibre-based cable network, which is already available
to some 67,000 homes in the region.
8.2
Commenting on the launch of the trials, Online Mediaæs chief executive,
Malcolm Bird, said: öAfter all the hype about multimedia and the
information superhighway, this is a real application, running into
consumersæ homes. It is a milestone for the multimedia industry and will
help establish digital ATM technology as the industry standard.ò
8.2
The technology involves linking a set-top box, which looks like a
smaller version of a video recorder, to the television set in peopleæs
homes. They will then have access to a variety of services from a
control centre in Cambridge. Multimedia telecommunications allows video,
voice, data and other services to be mixed at will on a single
telecommunications network.
8.2
The öon-demandò services on offer include movies and local news and
weather from Anglia TV. Subscribers can access these as and when they
wish and manipulate them Ö by fast forwarding, pausing and rewinding Ö
using a remote control as if the film were playing from their own video
recorder. Online Media is currently working with ITN to develop national
and international news programming.
8.2
Educational software applications will be available through the system,
from companies such as educational specialists Sherston Software and
another local firm, Cambridgeshire Software House. Anglia TVæs CD-ROMs
are also being converted to run on the system. Other services being
developed for the system include: interactive shopping, audio on demand,
music videos, sport and banking.
8.2
Games originally used on Acornæs 32 bit RISC computers are being
converted to run on the set-top box. In the future, another compelling
feature will be a range of games which can be played öacross the
networkò. With a football game, for example, several homes linked to the
system could be connected to the same game at the same time and would be
able to play as a team against another home or groups of homes. This
adds a whole new dimension of human interaction and team dynamics to the
game. Fantasy adventure games based on the same concept will be an
option in the future.
8.2
Barry Mallett, one of the first handful to receive the settop box today,
said: öWe are overjoyed to have been chosen for the trials and are
really looking forward to the prospect of being able to watch what we
like, when we like. The only problem I foresee is deciding which service
to try first!ò
8.2
The trial, intended to test the technology and act as a platform on
which to develop networked multimedia services, will initially be placed
in selected employeesæ homes in Cambridge. The aim is to install further
set-top boxes into many more homes of the general public by the end of
the year and to move into four figures by the end of 1995. Initially,
subscribers will not be charged for the service although an experimental
pricing formula will be introduced during 1995 to further test the
market. The consortium expects the venture to be fully commercial from
mid-1996.
8.2
Online Media, since its launch in July this year, has already had to
move into new offices to house its influx of staff Ö expected to be in
excess of 50 by January next year. Malcolm Bird says: öCambridge is the
ideal base for a dynamic, high technology company such as ours. Here, we
are surrounded by companies offering complementary technologies, with
which we can form powerful partnerships.ò
8.2
Online Media is a member of the Acorn Computer Group and has full
strategic backing from Acornæs parent company, Olivetti. It has been
established to provide interactive multimedia products for the markets
emerging from the digital superhighway including: interactive
television, video on demand and networked multimedia. Exploiting
technologies developed by the Acorn Computer Group and Olivetti, Online
Mediaæs first product is an intelligent set-top box designed to connect
a home television to the information superhighway. Alongside hardware
products, the company offers authoring systems, services and consultancy
in service development, as well as other areas. All Online Media designs
are available under licence.ááAá

Langdale CD
8.2
Nearly a year ago, I saw the first version of this Genesis application,
and the full CD version has now landed on my desk. This contains nearly
100Mb of information and photographs of the Lake District and is priced
at ú99 +VAT for a single user and ú149 +VAT for a site licence.
8.2
The CD also contains a Windows version of the same material so that the
one disc will do for both the Acorn range and the PC but I have not
managed to get it working on a PC card.
8.2
Genesis Professional?
8.2
I have had a number of people writing or ringing me up in the last few
weeks reporting bugs in either Professional or Project. I would like to
collate a whole series of reports about any bugs that you have found in
these programs in the next few weeks so that I can see someone from Oak
Solutions at Acorn World. If you have come across any bugs that I
havenæt mentioned below, please do give me a ring as this will enable me
to try and duplicate them on my machine and get some sort of list
together.
8.2
Known bugs and features: Computer hangs when trying to copy word frames.
Background colour on frames is different from background colours on page
when the same colour is chosen. CSV files are no longer supported.
Shared resources are no longer easy to find.
8.2
I had a phone call the other night about the fuzziness displayed by
fonts when placed on a transparent background. The gist of the problem
is that if you create a frame in Genesis and then place some text in it,
you can get a fuzziness around the outside of the letters. This is not a
problem with Genesis but I think it is a problem with the settings on
the font manager. Being none too technical myself, I wonder if anyone
has any idea on how to cure this problem?
8.2
Foreign formats
8.2
I have a had quite a few letters from readers about using foreign format
files in multimedia programs and how to convert a Genesis or Key Author
application between the PC and an Acorn computer. The most frequently
asked question is, öCan you author a multimedia application on a Risc PC
in the Acorn environment and then convert it to a PC version in the same
box?ò Well, the answer at the moment is that nobody I have talked to
seems to know! Acorn maintain it should be possible but Oak arenæt sure.
All we can do is wait for the PC chip to appear. As soon as it does,
then I will have a try. In the meantime, has anyone used a PC card in,
say, an A5000 to produce a PC version of either a Genesis or Key Author
application?
8.2
On the subject of foreign formats, there are a number of good PC PD
libraries around, and it is worth getting hold of their discs or even
better a printed catalogue of their material. Using !Translator, it is
fairly easy to covert pictures into sprites for inclusion in your own
applications. However, up to now, the conversion of sound samples has
been difficult. This has changed since the introduction of AudioWorks
from Computer Concepts. For most PC material, the standard format is
WAV, and if you want to convert it into Armadeus format, for Acorn
machines, just drop the sound sample onto the AudioWorks icon and save
out the new format.
8.2
To give you some idea of the possibilities, I have taken some material
from a PC CD and have constructed a quick Magpie application which will
be added to the Swap Shop Catalogue. On this monthæs disc, is a small
version of the Swap Shop catalogue. If you want the full details, send a
disc to the address at the end of the article.
8.2
Key Author and foreign formats
8.2
Following on from the above, I have been chatting with Peter Stibbons at
Anglia TV regarding their attitude to foreign formats. Many of the CDs
that they produce now include foreign format material on the same disc.
All this is set to go to the next logical development. At the moment,
you can produce an Acorn format file and then, using the PC version of
the run file, you can run it on a PC, without any conversion at all,
within certain restrictions. One of the major problems of converting a
drawfile into something that a PC can interpret has been overcome. The
only restrictions now appear to be on font conversion and Ace films
which the PC canæt handle. The Ace problem is overcome by converting
them to either MPEG or Quicktime films. Whatæs more, they also appear to
have overcome the problem of using the same disc in a Mac. At the
present moment, you can only produce a CD which will work on a Mac and a
PC, or an Acorn and a PC, but I donæt think the day is far away when the
same Key Author CD can be read and played by all three machines. The
good thing about this is that the native format will be Acorn! All you
budding multimedia authors may very well be in demand because as far as
I know, there is no other machine or software that will be able to
duplicate this.
8.2
I hope to visit Anglia TV in the coming weeks and take a close look at
not only MPEG files running but also the whole of their set-up and I
will report back in the next issue of Archive.
8.2
The Swap Shop
8.2
Just days after I submitted the copy for last monthæs issue, I was
inundated with applications! I received two Magpie binders from John
Pugh, one of our regular contributors. They are both aimed at National
Curriculum history topics: the Second World War and Britain from 1930-
60. Also, from South Australia, I have had two small Magpie binders, one
on the history of the Spitfire, and another on the Greek Language. Both
were created by Peter Russell of Memorial Oval Primary School.
8.2
Also added just in time for Christmas is a very good Genesis application
on Christmas Customs. This has extensive Maestro files of Christmas
Carols and looks at all our Christmas customs along with others from
around the world. If you want to order this one, either send me two
blank 800Kb discs or one 1.6Mb disc as this is a Genesis Professional
application which requires the new browser and GenLib.
8.2
I have also updated the ÉChurchesæ application with a whole load of
sprite files of real churches and features. (I got a video camera for my
birthday!) However, the size has grown to nearly 1.4Mb in Genesis format
so you will require a machine that can read 1.6Mb discs. I have also
converted ÉMan in Spaceæ and ÉAdvanced WIMP tutoræ to Magpie format.
8.2
At the moment, I am working on a binder on renewable energy that will be
available next month, but I am beginning to run out of subjects. To this
end, I would like to know what you would like to see as a multimedia
application. If you have any ideas, particularly if you have your own
art work, please do drop me a line with your suggestions.
8.2
I also noted the requests for beginnersæ articles in the last magazine
along with help on Paint. We do have multimedia applications that can
help you out with these problems. WIMP tutor is designed to be used by
those with little or no experience on Acorn machines. We also have a
ÉPaint Tutoræ and an ÉAdvanced WIMP Tutoræ which goes into more detail
than the basic tutor. All these applications are free and come with a
reader to allow you to run them without access to any of the multimedia
programs.

Monitors
8.2
Arthur Taylor has supplied a copy of his AKF85 monitor script which
works fine on my system, giving a very useful 1600╫1200 in 256 colours
(pixel rate 155MHz, but you must have 2Mb VRAM). This throughput is at
the limit of the VIDCá20 specification, so you use it at your own risk.
However, having said that, it works fine for me, providing sufficient
screen width for two A4 pages side by side. Also provided is a 640╫512
mode, which is chosen by the operating system, in preference to 640╫480,
when modes 20 or 21 are chosen.
8.2
Software compatibility
8.2
I now have a module provided by Colton Software (via Gerald Fitton),
which allows FireWorkZ to display deep sprites. Please note that this
will only work on the RiscáPC!
8.2
A number of people have written to report problems with FireWorkZ. This
does not, however, seem to be just on the RiscáPC, so I have sent copies
to Gerald Fitton for his comments.
8.2
Likewise, a number of people have reported problems with WordWorks as
supplied with Impression Style. I now have Style at Version 3.04 (31
June 1994) and so far have not found any of the problems reported with
earlier versions.
8.2
Keith Gardener has sent a long letter in which he confirms reports that
have arrived from a number of contributors Ö namely that some Basic
programs which ran OK on the Archimedes, now fail to run, some reporting
Éno room for Function/Procedure callæ or Étoo many nested structuresæ,
etc. Most people report that enlarging the Wimp slot has cured the
problem for them. Why should this be?
8.2
Following on from this, one program which ran with 16Kb on the
Archimedes, required 20Kb to run and then reported ÉMissing Endcaseæ,
which was correct! I asked Matthew Hunter at NCS about these issues, and
this was his reply...
8.2
öBasic splits the memory allocated to it into three areas. At the lowest
available address is the program itself, immediately above it is some
workspace for arrays. Growing down from the top of the available memory
is the stack. This is used to store variables, procedure calls and other
nested structures. Due to the reduced page size on the Risc PC, a
program could be allocated as much as 28Kb less than on one of the
earlier machines although the figure is likely to be closer to 12Kb.
When a program first loads, there is very little space needed for the
stack so the program begins to run, as more variables are used and
procedures are called, the stack will grow until it tries to overwrite
the workspace, giving errors like those above. When increasing the
wimpslot, as a first estimate, round it up to the nearest multiple of
sixteen Ö this allocates more space to the stack, which should solve the
problems.
8.2
öI have also looked into the case of the ÉMissing Endcaseæ! By using a
quick program, I tested the operation of the CASE statement, but could
find no difference with the new version of Basic.
8.2
CASE c% OF
8.2
  WHEN 0 : PRINT öCase endingò:END
8.2
  WHEN 1 : PRINT öOh Dear ò;
8.2
  WHEN 2 : PRINT öCase endingò
8.2
END
8.2
öWithout knowing what the CASE statement was testing, I cannot be sure
but I suspect that an unexpected result occured. The above program will
report ÉCase endingæ with no errors for c%=0 and c%=2. It will report
ÉOh Dear Missing ENDCASEæ when c%=1, and simply ÉMissing ENDCASEæ for
any other value.ò
8.2
Hardware and software news
8.2
I have now received my updated TurboDrivers for the Canon BJ230 (v4.00
17th-Aug 94) and can report that the combination of this plus Impression
Style and the RiscáPC, produce printing at a speed and quality which
have to be seen to be believed. The average single page letter is now so
quick to render, that there is a pause of only about three seconds
before you have control back!
8.2
I have installed a Toshiba XM-3401B CD-ROM on my HCCS Ultimate SCSI
Micropodule and it performs well. (Ultimate v1.10, SCSI Driver v2.06,
SCSIFS v2.06, SCSIFiler v2.02, CDFSResources v2.20, CDFSdriver v2.20,
CDFS v2.20, CDFSFiler v2.20.)
8.2
Now I need the PC486 card with CD-ROM drivers so that I can use the new
CD-ROM RS Components Catalogue in the office! This will save vast
amounts of time and is, for me, the first sign that this format is
coming of age. It allows three A4 catalogues, which together are over
two inches thick, plus hundreds of data sheets, to be replaced by one
half full disc! The disc contains all the textual information, colour
illustrations, prices and quantity discounts, all the engineering
information sheets, generates and prints the order for you and allows
you to search for what you want, without wading though all that paper.
Brilliant!
8.2
The ARM Club have produced a most useful utility (Game On), which allows
games etc, which would not work, to operate successfully. I have sent a
copy of the freeware database of games with which it works to Paul for
inclusion on the monthly disc. I may have a review by next month.
8.2
Charles and Deborah Woodbridge have purchased a new HP LaserJet 4P to go
with their RiscáPC and comment that, with the Acorn printer definition
file, the results are excellent and I can vouch for this as the prints
they sent are excellent.

Readersæ comments
8.2
From Jim Nottingham: öHaving recently bought an Acorn AKF85 to go with a
Risc PC, I have to say that, after all the hype, I was a little
disappointed with its display quality in comparison with an Eizo F550i
Iæve been using on an A540. So I thought Iæd see how the Eizo ran on the
RiscáPC, using the standard 9-pin lead with a 9/15-pin adaptor from NCS.
8.2
öThe book says for an alternative (i.e. non-Acorn) monitor, set ÉAutoæ
in the Screen configuration under Monitor type. Result? Nothing.
However, after a little trial and error, I found that by making the Eizo
think it was an Acorn monitor by setting ÉAKF85æ, it works a treat with
a noticeably sharper display than the actual AKF85. This dodge may work
for other Éforeignæ monitors.ò
8.2
From Stuart Bell (edited): öClearly, the issue of compatibility with the
RiscáPC will be important for those with older Acorn machines who expect
eventually to upgrade their machine. Will it have an effect on their
purchase decisions before they upgrade? And, how will existing equipment
perform on the new platform?ò
8.2
I think that Stuart is worried that his investment in accessories for
the Archimedes will be wasted. However, I feel that you only have to
look at the Acorn ÉBBC Masteræ which is still widely used, years after
it went into production, to realise that the Archimedes probably has ten
or more years of life left in it, and that there will still be a healthy
market in second hand add ons for some time yet.
8.2
Requests for help
8.2
This is also from Jim Nottingham (of scanner article fame): öHas anybody
managed to get an AKF85 or other monitor to work from the RiscáPC, using
the BNC connectors? Neither my AKF85 nor my Eizo F550i seem to want to
play. I am using what is listed as a standard PS/2 monitor lead, with
BNC plugs at one end and a 15-pin plug at the other.ò

Risc-DOS Column

8.2
It appears that the earliest anyone is likely to see a co-processor card
is at the Acorn World Show. Even then they are unlikely to be on sale. I
understand that the ASIC (the clever chip that does all the hard work
arbitrating between the two different architectures) is taking longer
than expected to produce. It is hoped to have the first, limited,
production run a few days before the show. This being the case, I have
written this monthæs article as a (hopefully ex) Windows and DOS users
first impression of the new Risc PC.
8.2
A new toy
8.2
As I write, I am sitting in front of a brand spanking new Risc PC. It
arrived in two boxes. One containing the computer Ö fairly manageable.
The other containing the 17ö monitor Ö instant back-strain. I followed
my usual course of action when faced with any new item of an electronic
nature. I unpacked it, plugged all the cables into the most likely
looking sockets and switched on. Luckily, and it speaks volumes for the
ease of use and logical design of the Risc PC, everything worked first
time and I was soon presented with the RISCáOS desktop.
8.2
After an initial go at configuring the computer to my liking, I
proceeded to install my core suite of software. These are the three
basic pieces of software I need on any computer. Word processor,
spreadsheet and database. Not having any experience on an Archimedes
since the earliest Arthur OS version, I was a little out of touch.
Fortunately(!), my Risc PC had been on order for approaching three
months, so I had had plenty of time to study magazine reviews. I was
certain which word processor I wanted Ö Impression Publisher. It
consistently features in magazines and has the greatest level of support
from third parties.
8.2
The choice of spreadsheet was a little more complex, but following a
couple of positive reviews for the new Schema 2, my choice was made, it
has full macro facilities, something I consider essential in a
spreadsheet.
8.2
The choice of database has been harder. Despite several reviews in the
Acorn press, I am still undecided. I currently have Impact Pro and
Squirrel 2 on my hard disc and whilst both have their strengths and
weaknesses, neither is perfect. There again what software package is? I
am also going to look at DataPower and S-Base 2. I am sure, one of them
will be suitable for my purpose.
8.2
After a few days, the 17ö monitor, in a 1024╫768 by 256 colour mode, had
my new desktop proudly displayed. The applications and utilities I had
chosen to appear on the iconbar after start up were all in their proper
places. These are FontDir, Printers (for my LaserJet 4), ArcFax and
Dustbin Ö on the left hand side and Edit, Keystroke, ImpactPro, Schema 2
and Impression Publisher on the right hand side. It looks good, or to
quote from The Mask, öreallyyyy smokinnnn!ò.
8.2
RiscáPC versus Windows PC
8.2
But, how does it compare to the Windows PC I had been using? You may
remember I have a well specified 66MHz 486DX2 with 16Mb RAM with an
accelerated (S3 super VGA) display driving a large screen monitor. My
Risc PC is an ACB45 (two slices, 8Mb RAM and 1Mb video RAM), to which
Iæve added a further 16Mb RAM SIMM Ö taking total memory to 25Mb (donæt
forget the Risc PC will use any spare video RAM as ordinary RAM). You
may wonder why I have chosen to have so much RAM on a system that works
well with 8Mb. I intend to do some photo processing at a later stage,
once I have decided upon the most suitable software (PhotoDesk sounds
favourite at the moment, although I intend to have a look at as many as
possible at the Acorn World show). I also believe I will need a large
quantity of RAM in order to get Windows running when the co-processor
card arrives.
8.2
Although Microsoft claims that you only need 4Mb to run Windows, my own
experience shows that you need at least 8Mb and preferably 16Mb in order
to get anything like reasonable performance, whilst running two or more
software packages. On top of the Windows requirement, there will also be
some memory required for the video display and running the RISCáOS
desktop. My own feeling is that you will need at least 16Mb if you wish
to multitask between RISCáOS software and Windows software. And,
finally, as already mentioned above, I like all my main applications to
be loaded on the iconbar from the minute I switch on.
8.2
My initial reaction is that the Risc PC feels faster than my Windows PC
in most respects. The screen updating, the way windows are moved around
in real time, the loading of graphics into Impression all convey a
feeling of smooth sophistication that is somehow lacking in my Windows
PC. Not everything is as wonderful, however. Printing seems to take a
long time. I have ordered the Ace Pro Drivers, and will see what
difference these make once they arrive and I have had a chance to set
them up. (Iæll send you a CC Turbo Driver, Simon so you can compare that
as well. Ed.) I was expecting more in the way of crashes than I have so
far experienced. Maybe I am lucky, but the few problems I have had have
all been as a result of using incompatible programs, often older
software from PD or magazine discs. The main applications I have used
have all been remarkably stable Ö notably more so than my Windows PC
applications.
8.2
Like a duck to water, I found the operation of the RISCáOS desktop
fairly easy to pick up. There are one or two differences from Windows,
the most obvious one being the use of a three button mouse and the
middle Émenuæ key instead of the menu bar at the top of each application
window. At first I found I was moving the mouse up to the top of the
window and had to remind myself to use the middle button. But within a
couple of days I was using my middle finger like a natural. It is a
definite improvement once you get used to it Ö the menu is always
context-sensitive and appears right where you want it to. Context-
sensitive menus have only just been discovered fairly recently, on an
application by application basis using the right hand mouse button, in
Windows. In RISCáOS, this means that valuable screen space is not taken
up by the menu bar. I still find it hard to operate the Adjust button
with my third finger, especially when double-clicking to open a
directory so that the parent directory closes. (Thatæs interesting! I
hold the mouse between thumb and third finger and then move my middle
finger across between menu and adjust. I wonder what other people do?
Ed.)

Iæve had the Risc PC for a few weeks now and Iæm delighted with it! Itæs
everything I had expected from reading Acornæs promotional material and
the reviews in various magazines.
8.2
Chicago, Chicago, wherefore art thou...
8.2
Chicago or Windows95 as it is to be known, probably, will not see the
light of day before next summer. All Microsoft will say is Ésome time in
the first half of the yearæ. Why should I, or anyone else, be interested
in Chicago? Well, if one is interested in the 486 co¡processor, it must
be in order to run DOS and/or Windows software. Windows95 is a full 32-
bit operating system that will work on 386 or higher processors only,
and so will cure all the memory problems of DOS. Or will it?
8.2
Using Windows95 to run 32-bit software will certainly bring an end to
the 640Kb DOS memory limit within Windows. If you are going to be
running any Éolderæ Windows or DOS programs that rely on software
drivers loaded by autoexec.bat or config.sys, you may still have
problems. The reason is, that in order to remain compatible, Microsoft
have had to keep autoexec.bat and config.sys as the means for loading
some older drivers Ö programs expect to find them there and often load
their own drivers there as part of their installation process. Most of
the large software companies, the likes of Novell, Symantec etc, will be
releasing 32-bit device drivers for the new Windows95. But until they
do, if the particular driver you rely upon comes from a less expeditious
company or the program is no longer supported, you will still find
yourself having to play the memory management game.
8.2
And finally...
8.2
I am going to the Acorn World Show on Friday 28th October and hope to
get my first look at and, if I can be persuasive enough, my first try of
the co-processor. Following this, I hope to get my hands on one of the
first cards to be released. This being the case, I may well have
something more concrete to report about in the next issue. Until then,
good computing!ááAá

ColourPicker in RISC OS 3.5
8.2
Elliott Hughes
8.2
Those who have used a RiscáPC may have noticed that Draw now supports
24ábit colour. The format of the drawfile has always allowed it to
represent true colour, but Draw originally only allowed the user to
choose an 8-bit colour.
8.2
When I first saw the new colour selection dialogue boxes (in chapter 6,
öUsing colour in applicationsò, of the RiscáPCæs user guide), I assumed
that these new dialogues would be available to users of the latest
RISC_OSLib only. Tired of waiting for both the new volume of the PRM and
the new C/C++ compiler, I noticed that, as well as öColour Selector
1.61ò (ColourTrans), RISC OS 3.5 has a module öColour Picker 0.15ò
(ColourPicker).
8.2
Using the information in OSLib, written by Jonathan Coxhead of Acorn, I
was able to work out enough to add ColourPicker dialogue boxes to my own
programs. OSLib is copyright Acorn Computers, but is not an official
Acorn product. For information on getting a copy of OSLib, see the end
of this article.
8.2
Introduction
8.2
ColourPicker allows a program to offer a dialogue from which the user
can choose a palette entry using any available colour model. The program
can then use ColourTrans to calculate the best colour .
8.2
An application using ColourPicker does not need to know anything about
colour models or the capabilities of the current screen mode.
ColourPicker is capable of responding to requests for interactive help.
8.2
Overview
8.2
As with ColourTrans, the term Épalette entryæ refers to öa word that
contains a description of a physical colour in red, green and blue
levelsò. A colour model is a way in which the user can specify colour.
The three models built into RISC OS 3.5 are RGB, CMYK and HSV. (These
are explained in both RiscáPC and Impression user guides.)
8.2
Two SWIs allow colour models to be registered and deregistered with
ColourPicker.
8.2
Four SWIs allow the application to open, close, update and read a
ColourPicker dialogue.
8.2
Other SWIs allow the application to pass requests for interactive help
to ColourPicker and to interface new colour models to the ColourPicker
front end.
8.2
ColourPicker_OpenDialogue   (SWI &47702)
8.2
Creates and opens a colour picker dialogue
8.2
On entry
8.2
  R0 = flags
8.2
    bit 0 set Ö dialogue is transient
8.2
    bit 1 set Ö dialogue hangs off a menu
8.2
  R1 = pointer to block containing information about the dialogue
8.2
The format of the block passed is as follows:
8.2
  +0  flags:  bit 0 set Ö offer the user the None á  icon for
transparent colour
8.2
      bit 1 set Ö use the transparent áá  colour as the initial
selection
8.2
      (there may be others, but they á  havenæt been discovered)
8.2
  +4  pointer to zero-terminated title of dialogue box
8.2
  +8  min. x
8.2
  +12  min. y
8.2
  +16  max. x
8.2
  +20  max. y
8.2
    These give the initial position of the dialogue box. Only min. x and
max. y seem to be used. They give the position of the top-left corner of
the dialogue box.
8.2
  +24  x scroll offset Ö no idea when itæs used
8.2
  +28  y scroll offset Ö no idea when itæs used
8.2
  +32  palette entry of colour selected initially (ifábit 1 of +0 isnæt

8.2
  +40  colour model number of initial colour model:  0áá  RGB
8.2
        1áá  CMYK
8.2
        2áá  HSV
8.2
This SWI is used to initiate the colour selection. The ColourPicker
module takes over and keeps in touch by sending messages to your task.
The two most important are Message_ColourPickerColourChoice (&47700) and
Message_ColourPickerCloseDialogueRequest (&47702).
8.2
Message_ColourPickerColourChoice
8.2
(Message &47700)
8.2
This message indicates that the OK button has been clicked to accept the
current colour. The message data is as follows:
8.2
  +20  1 ë transparent selected
8.2
    0 ë colour selected
8.2
  +24  palette entry of colour selected (if +20 is 0)
8.2
When this message arrives, the dialogue box dismisses itself. You need
only take whatever action is relevant to your application (and wait for
the next message to arrive).
8.2
Message_ColourPickerCloseDialogueRequest
8.2
(Message &47702)
8.2
This message indicates that either the OK button has been clicked (and
youæve already been told about the colour selected) or that ColourPicker
wants its dialogue box removed (perhaps because Cancel has been
clicked). To respond, call SWI ColourPicker_CloseDialogue with R1 =
contents of the 20th byte of the message block.
8.2
ColourPicker_CloseDialogue
8.2
(SWI &47703)
8.2
Closes a colour picker dialogue which is in progress.
8.2
On entry:
8.2
  R0 = flags Ö use unknown
8.2
  R1 = pointer to block containing information about the dialogue
8.2
This SWI is used to remove a colour picker dialogue box.
8.2
Conclusion
8.2
The RISC OS 3.5 ColourPicker is a promising step forwards. By providing
the code to implement RGB, CMYK and HSV colour selection (and the
possibility of adding new models), Acorn is making it easy to provide a
consistent and appropriate user interface. Itæs possible that Computer
Concepts will find an excuse to be different Ö they often do!
8.2
I think Iæll go and look at Wimp_TextOp next. Iæm sick of the system
font.
8.2
Getting hold of OSLib
8.2
OSLib is öa set of functions and C headers to provide complete coverage
of the RISC OS application programmeræs interface in Cò. The author
claims it provides öa very convenient interface to the RISC OS
programmer, since all the facilities of the compiler that is currently
being used are available to catch errors. It is conceptually very small,
in that it is completely documented by [a readme file] and the PRM. As a
bonus, code written using it is smaller and runs faster than code
written using other meansò.
8.2
Iæd go along with that, and suggest that anyone writing for RISC OS in C
or assembler should get themselves a copy. Itæs easier to write style
guide compliant applications with OSLib than with RISC_OSLib, which is a
poor reflection on RISC_OSLib. Maybe with the new compiler...
8.2
OSLib is available via anonymous ftp from micros.hensa.ac.uk. If you
have a WWW client, you can also try http://micros.hensa.ac.uk/. OSLib is
quite large, but it may even be available from some of the PD
libraries.ááAá

Gerald Fitton
8.2
As Gerald will explain, he is changing the direction of his regular
(and, I must say, much valued) articles. The new name is meant to be an
abbreviation for öDocument Preparation Lineò Ö the best description that
we could find for the general area that he is going to cover. Ed.
8.2
I know of half a dozen people who can produce all the documents they
want with no more software than that excellent wordprocessor Wordwise.
Our editor is familiar with that package and has produced many excellent
booklets explaining how to make best use of it. (Sadly they are all out
of print now. Ed.) The hardware used by these half dozen acquaintances
is a 32KbáBBCáModeláB computer which they bought ten or twelve years ago
together with a printer such as the dot matrix FX80 Ö a machine which
went out of production in the mid 1980s.
8.2
Most of us who read Archive, even if we know of Wordwise, will not be
using that combination of software and hardware (though I have a recent
letter which extols the virtues using Wordwise on the Archimedes as an
intermediate format for Éportingæ documents from one platform to
another); probably weæve got a combination of such packages as Artworks,
PipeDream and Impression Style and hardware which contains the
RISCáOSá3.1 operating system as ROM.
8.2
In the next few months, I would like to consider why people upgrade from
one hardware/software system to another. Iæm going to explore that with
you and, I hope, help you to rationalise your strategy for hardware and
software upgrades. I shall concentrate on those hardware/software
systems for which the first use is document production.
8.2
Within my definition of document, I include spreadsheets, letters,
invoices, and those documents which might be described under headings of
DTP and drawfiles. I specifically exclude games, program development,
and hardware and software that are used for musical or mechanical
purposes. I shall cover any kind of document production hardware and
software; I shall concentrate on looking at how such a system appears to
the user and buyer.
8.2
PipeLineZ to DocLine
8.2
In the last edition of Archive, there was a comment that, although the
contents of PipeLineZ often contains material which would interest Énon-
Coltonitesæ, it is difficult to persuade those who donæt have PipeDream
or Fireworkz to read it! The editoræs suggestion is that it might be a
good idea to change the name. I agree!
8.2
In fact, about one third of my Archive generated correspondence is from
Énon-Coltonitesæ and much of that correspondence is of great interest to
me, is complimentary towards PipeLineZ and is of great general value. I
would like to include more of such correspondence in Archive. My opening
paragraphs and the change of title this month is intended to catch your
attention and persuade you Énon-Coltonitesæ that this column is worth
reading even if Colton Softwareæs products do feature heavily herein.
8.2
Before I launch into my main topic for this month, there are a few
hangovers from past volumes of Archive which need mentioning. Even there
youæll find parts of interest to Énon-Coltonitesæ which introduce my
main theme for this month.
8.2
Stamps
8.2
The following is part of a letter I received from MráAáGáRimmer. The
programs which he mentions are on the Archive monthly disc.
8.2
öSince receiving your letter, I have bought a copy of Fireworkz, and
enclose on disc a copy of a program to choose the minimum number of
stamps for any given postage amount (assuming that all the current
values of stamps Ö or at least those listed in your April contribution
to Archive Ö are available). I also include an improved version of a
Basic program that does the same thing Ö but faster!
8.2
öI recently got PipeDream 3 free from Risc User on paying for a yearæs
subscription to their monthly disc. It seems to have the advantage over
Fireworkz that, by using its own printer-driver, you can print letters,
etc, much more quickly on a dot-matrix printer as compared to the
painfully slow graphics printing using !Printers. However, for my
letters, I use DeskEdit with a text-only printer-driver.ò
8.2
In an earlier letter, MráRimmer sent me a PipeDream solution which he
created using PD3 (but which Éworksæ in PD4) Ö that, too, I include in
the Stamps directory of the Archive monthly disc.
8.2
MráRimmer uses a range of software from Basic to DeskEdit, choosing the
package most suitable for the application he is working on. In line with
the philosophy which I wish to promote, he has my encouragement to
continue with this strategy.
8.2
Cross checks
8.2
I have received a great deal of correspondence on this subject since I
mentioned it. Essentially, a cross check is a tactic for ensuring that a
spreadsheet hasnæt made an error. The method is to use the same data for
two different sets of calculations which are designed to give identical
answers only if there are no mistakes. One problem with binary
arithmetic (to which I have referred in an earlier Archive PipeLineZ
article) is that most decimal values are truncated and hence stored as
approximations, and as a result of this truncation, the two calculated
results which should be identical are, more often than not, only
approximately equal. An obvious cross check, testing for exact equality,
may fail even when there is nothing wrong with the spreadsheet. This is
not a characteristic peculiar to the products of Colton Software. The
effect can be reproduced with other spreadsheets (as my non-Coltonite
correspondents have delighted in telling me) as well as in something as
basic as Basic.
8.2
At this stage I must record my thanks to Denis Howard for the
inspiration which has led eventually to the formula which, between us,
we developed for checking if two values are Énear enoughæ the same. I
have included on the Archive disc a directory called CrossCheck which
contains files in PipeDreamá4 format. These files will load into
Fireworkz. For those of you using a different spreadsheet package the
solution is contained in the following lines which are in the form of a
PipeDream or Fireworkz custom function:
8.2
...function(ösame_numberò,öfirst:numberò, ösecond: numberò)
8.2
...result(if(abs(@first-@second)/(@first+ @second)<(1e-
16),öOKò,öErrorò))
8.2
What this formula does is to find the ratio of the difference to the sum
of the two Éequalæ numbers. If we call the Éequalæ numbers x and y then
we calculate the absolute value of (xáÖáy)/(xá+áy). We use this ratio,
rather than just the value of  (xáÖáy), so that we can make allowances
for Élargeæ and Ésmallæ values of x and y. We find the absolute value so
that we can Éget ridæ of negative values. Then we compare this ratio
with the small positive number 0.000á000á000á000á000á1. If the ratio is
smaller than this small number, x and y are Énear enough equalæ for
there to be no errors in the spreadsheet.
8.2
By the way, PipeDream text files (such as the [ReadMe] explanation of
the way in which this Cross Check works) will load into Edit. If you
have RISCáOSá3, the easiest method of loading almost anything into Edit
is to hold down <shift> and double-click on the file.
8.2
PipeDream to Psion
8.2
If you have problems porting files to and from the Psion, the files on
the Archive disc in the directory PD/Psion will be of interest to you.
The Éconversionæ process mentions Lotus and other Éforeignæ formats so
it is not a PipeDream only article. Although Ian Williamson uses
PipeDream files for his example, if you write to him heæll do his best
to explain Éhow to do itæ with other format files. His address is in the
PipeDream format [ReadMe] file on the Archive monthly disc. Load it into
Edit if you donæt have PipeDream.
8.2
Computer systems
8.2
Now to the first part of a series which I will develop during the next
few issues of Archive, namely the way in which you can rationalise your
strategy for upgrading your computer system. I hope that through this
series of articles, you will benefit from my personal experience of
upgrading in the same way that I have benefited from comments made to me
by other people.
8.2
It seems a long time ago but I suppose it canæt be more than 15áyears
ago (1982, wasnæt it? Only 12 years! Ed.) that I bought an Acorn BBC
model B microcomputer. It had no hard disc, no printer and the TV
doubled as a monitor! Now I have an A540 (before the RiscáPCs appeared,
this was the Étop of the rangeæ machine) and one of the first A440
models to be produced (donæt confuse my A440 with the later A440/1 etc
series). I shall buy a RiscáPC later when I can (a) afford it and (b)
justify the expenditure!
8.2
Letæs start with some general principles. Firstly, think in terms of the
whole system rather than just the Écomputeræ box. By this, I mean think
of the monitor and printer (and even your Ésoftwareæ packages) as
upgradable parts of your overall system. My first message to you is that
a good printer and a good monitor both make up a substantial proportion
of the overall cost of your system so thinking about what you want is at
least as important as thinking about the Écomputeræ box.
8.2
Letæs start with a general discussion of printers, using it as an
example of the Érightæ way to think about upgrades.
8.2
Printers
8.2
My first printer was a 9-pin Epson FXá80 and (important to my
discussion) it cost as much as the BBCáB computer. I bought it before I
upgraded from cassette to a floppy disc drive. However, that printer saw
me through an upgrade to a BBC Master computer (as did the disc drive)
and I used it with the A440 Archimedes for a year or two before
relegating it to a tractor feed label printer. There is no doubt in my
mind that the FXá80, although one of the more expensive printers at the
time, was better value for money than was my BBCáB computer. This is not
to say that the BBCáB was not good value; it was good value. The FXá80
was even better value because it saw me through three computers: the
BBCáB, Master and A440.
8.2
My second printer was an Epson GQá3500 bought over five years ago. It is
a laser printer and produces better quality at 300ádpi than the 9-pin
FX80 ever could. It still exists but Iæve Élentæ it to my son for use
with his 486áPC; I used it for quite a while, both with my A400 and then
with my A540. If I still had it, I would be using it now and I would be
using it with my RiscáPC (the one I havenæt bought yet). Once again,
that printer cost as much as an Archimedes computer but it saw use with
two (A440 and A540) and is still going strong now with a third computer.
Let me repeat (in the hope of convincing you) that buying a good printer
is a Ébetteræ or longer term investment than buying a good computer such
as the Archimedes A540.
8.2
I am not yet convinced about the printer Iæm currently using. It is of
the colour inkjet type. The model is the Integrex ColourJet Seriesá2
which has a resolution of 300ádpi like the laser printer. (It does not
produce quite as good an image Ö but itæs pretty close.) The Integrex is
an HP 500C compatible which I bought for two reasons. One is that I
wanted to experiment with colour and the other is that I often print one
or two labels at a time on an A4 sheet of 18 labels. With the laser
printer, I was using a page worth of toner for a couple of labels; with
the inkjet I use only the ink needed to produce the label Ö so it works
out to be a little more economical than the laser. Nevertheless, I
expect that the Integrex will see me through at least two upgrades to my
Émainæ computer hardware and, at much less than the cost of a computer,
it is still a better investment than the A540 which (currently) outputs
to it.
8.2
I hope you will have gathered, from the examples I have quoted for
Printers (as part of an upgradable computer system), that it is not just
the cost of an item which is important but you also have to judge how
far into the future itæs going to last. Whether a piece of hardware Ö or
for that matter, software Ö is a good investment must include a
(difficult to estimate) time element. I hope that this series of
articles will help not only Coltonites wondering about upgrading to
Fireworkz but also non-Coltonites wondering about Ö letæs say Ö
monitors!
8.2
Monitors
8.2
The technical considerations of choosing a new monitor have been covered
in earlier issues of Archive but I hope that youæll agree (when youæve
read it) that what I have to say complements those articles rather than
reiterates the information therein.
8.2
Back to my personal history. I soon replaced the TV, which I used for
the BBCáB, with a proper monitor. It was one of the Microvitec series
but I canæt remember which one. At the time, it cost about the same as
the BBCáB had cost me but it served me well with the Master I bought to
replace the BBCáB and is still working well as part of the system which
I passed on to a friend.
8.2
I bought my A440 with one of the Acorn cheaper Éstandardæ monitors but I
soon bought a multiple scan rate monitor (often referred to as a
Émultisyncæ) to replace it. The multisync I bought is the Eizo 9070S 17ö
Flexscan which, although unused, was available at about half price
because it was soon to be replaced with a later model! Nevertheless, the
Eizo cost me about the same as the computer hardware currently being
sold by Acorn.
8.2
I am still using that Eizo now with my A540. In the main I use it in
mode 102. This is a Éspecialæ mode provided in software by Atomwide as
part of their !VIDCmodes and !VIDCplus utilities which is available on
NCS Utils Disc N║1. Let me say more about modeá102 since it is relevant
to the specifications of current (and future) monitors. I make no
apology for referring to PipeDream documents in my discussion because,
even if you donæt have PipeDream, by thinking öEditò instead, Iæm sure
that youæll get my point.
8.2
The Atomwide modeá102 allows me to use PipeDream documents which are 136
system font characters wide without any of the document disappearing off
screen. The Édepthæ (or should it be the height) of the screen allows 50
(system font) lines of any PipeDream document to be displayed. This is
almost twice as Éwideæ and twice as Édeepæ as a modeá12 screen (the
modeá12 screen will display Ö in system font Ö a PipeDream document
which is 72 characters wide and 26 lines deep). You will see that the
Éareaæ of the desktop displayed in modeá102 is about four times that of
a modeá12 screen.
8.2
This large desktop area is the biggest single benefit I have gained from
using a multisync monitor. The Éoldæ standard 14ö monitor might have
been OK under the Arthur (single-tasking) operating system but, once it
became possible to put many windows on the screen and to have more than
one application running and to have transfers of data from one (say
Draw) to another (say Impression), then a bigger desk top area was not a
luxury but a necessity.
8.2
Although the Eizo 9070S is no longer available, I expect that I would be
able to use it with my RiscáPC (when I buy it). I donæt expect to
transfer the Eizo to the RiscáPC because I shall probably buy a new
monitor with that machine and keep the A540 and Eizo as my second
machine.
8.2
Buying a monitor
8.2
I recommend that you do not buy a Éstandardæ (fixed frequency) SVGA
monitor but a multisync. This is because the SVGA standard wonæt last
into the future as well as a good multisync will. Generally, if you buy
a good 17ö multisync monitor now then it should last you through at
least two computer upgrades. (This is true even if you were to change to
a Windows PC machine where the SVGA standard is seriously obsolescent
and where sales of multisync monitors are on the rise). I know that a
17ò multisync costs more than a Éstandardæ monitor (or an SVGA monitor
for that matter) but I do recommend it to you on the basis that it will
be a good investment Ö indeed, if I had the choice of buying either a
good 17ö multisync or upgrading from, say, an A5000 to the RiscáPC as an
investment in future-proofing, Iæd buy the multisync!
8.2
If I were a Énormalæ user with a good multisync, then I would register
as an ÉAcorn Enthusiastæ; that registration would entitle me to order a
RiscáPC computer without a monitor at a reduced price Ö I would use the
Eizo with the RiscáPC.
8.2
So what is a Égoodæ multisync? Iæve already told you what I think is the
major advantage of using a multisync; it is that you have a larger
desktop area. It is possible to create large desktop area modes for use
with a standard 14ö monitor but, with such a monitor, this larger area
will be of no use to you. This is not just because everything is smaller
(after all you could get closer to the screen) but because the screen
itself doesnæt contain enough dots per inch to resolve the fine detail
your larger area mode has created.
8.2
With a standard 14ö monitor, you might try the Acorn modeá35. It doesnæt
really show you what I mean but itæs a step in the direction of
enlarging the desktop area (in !Edit) from 80╫32 system font characters
to 96╫36 (about 20% increase in each direction). If you have the
Computer Concepts !NewModes (supplied with Impression) then you can try
their modeá90 which gives a desktop area of 160╫64 system font
characters. I find it unreadable when I try it on my A440 with a
Éstandardæ 14ò monitor because the dpi resolution of the monitor wonæt
cope with the fine detail created by the software.
8.2
What size?
8.2
If you are serious about CAD or DTP and really need a very large desktop
area, you might consider buying a 20ö monitor. At present, the prices
are, in my opinion, rather high for non professional use (but see my
comment in a later paragraph). I donæt recommend 15ò because the
improvement is minimal. Much more affordable, and a good compromise
between cost and Éthe bestæ is a 17ö multisync. With a 17ò monitor you
will, like me, be able to use a desktop area of about twice (in both
directions) that of modeá12. I would have liked just a fraction more so
that I could fit two 72 character wide PipeDream documents side by side.
Iæve been told by an Éexpertæ that modeá102 is about as far as it is
safe to go with a 17ö monitor. The expert I consulted understands the
fine detail of the technical articles recently published in Archive Ö so
I believe him.
8.2
Line scan rates
8.2
Understanding what is a good range of line scan rates is usually
presented as a difficult problem and one difficult to resolve. Let me
tell you why and then Iæll tell you my views. The old BBCáB was designed
to use a TV as a monitor so that the line scan rate was about 15kHz
(about 15000 lines per second). The modes used by the BBCáB are
available on the Archimedes. For technical and marketing reasons (Yes!
Itæs the IBMáPC syndrome again!) nearly all the better multisync
monitors have a minimum line scan rate of about twice this, 30kHz. The
consequence is that you canæt actually use modeá12 with a monitor having
a 30kHz+ line scan rate unless you cheat and fool your system into
believing that it has to scan twice as fast as it needs to. This is
effected with software such as that which used to be provided by
Atomwide as !VIDC but is now available from NCS on Utilities Disc N║ 1.
8.2
Here is my view. If you buy a multisync, it is unlikely that you will
want to use these 15kHz modes except for running a few special (old)
packages. I suggest that you get the !VIDC software for those few
occasions when you might need a 15kHz mode and forget all about
including low scan rates in your specification. Think of future-
proofing. If you use old software which needs these low modes (for
applications other than document production) then think about upgrading
the software!
8.2
Frame refresh rates
8.2
If you have RISCáOSá3.1, you will find that the modes included by Acorn
run at 50Hz (50 frames per second), 60Hz, 64Hz and 70Hz. The Video
Electronics Standards Association (VESA) have studied the phenomenon of
flicker (see last monthæs Archive article in the RiscáPC Column) and
they recommend that monitors be constructed using phosphors which
persist for a length of time which requires (and thus implies) a minimum
frame refresh rate of 72Hz. Because of this, I would expect that 72Hz
will become a minimum standard for any future extension of Acornæs
modes.
8.2
I have been told that the standard for digital television is to be
100Hz, so I would expect many more monitors having frame refresh rates
of 100Hz than there are at present to come on the market soon. In the
Windows PC market, refresh rates up to 100Hz are being discussed
regularly.
8.2
Yes! In spite of my proclaimed naivety, I do know that video memory and
video bandwidth come into the equation, but the thrust of my article is
future-proofing so I say öLetæs assume that video memory and video
bandwidth will increase Ö have we bought a monitor which will take
advantage of these advances in video memory and bandwidth when they
appear?ò
8.2
Perhaps a more important consideration is that digital television
technology will use computer video memory and monitor technology rather
than the current analogue circuitry. It seems certain now that Acorn
have an eye on this market with their MPEG second processor board and
new multimedia offshoot. If so, then new Acorn modes are likely to have
a 100Hz refresh rate. Having said all this, I hope youæll see why my
recommendation to you is that you buy a 17ö monitor which will run at a
100Hz refresh rate (and more) if you want it to be an investment for the
future.
8.2
My recommendation
8.2
I have looked at the specifications of what is available at the moment
in 17ö monitors even though I havenæt bought one yet. The Idek Iiyama
Visionmaster 17 is the only one I have discovered so far that has a
refresh rate of 100Hz when running with the largest desktop area
currently usable on a 17ò. Others (I donæt see them in the NCS
catalogue) will run at 100Hz but only with a reduced area. The
implication of this 100Hz at a large desktop area is that there is a
margin for even larger desktop area modes at lower refresh rates if
appropriate software (and internal hardware) is forthcoming from the
likes of Acorn or Atomwide.
8.2
This Idek monitor has a dot pitch of 0.26ámm, which is about the
smallest (best) available on other monitors Ö because of this, I would
expect that the resolution of the large desktop area would be good (i.e.
not grainy) to look at. It is by no means the most expensive of monitors
Ö in fact it is cheaper than many. NCS are selling it at about ú694
inclusive. You may be able to get one at somewhere between ú550 and ú650
if you shop around but remember that part of the price charged by NCS is
built in to provide you with service if you have a bad experience. One
of the things I tell my students at College is that I would never buy
insurance from a company that sells it so cheaply that it canæt make a
fair profit! You get one guess at why.
8.2
If you are buying a RiscáPC from NCS then, for an extra ú400, they will
provide this Idek instead of the Acorn 14ö AKF60. If you directly
compare this Idek with the Acorn 17ò AFK85, you will find that the dot
pitch of the Idek is slightly smaller (good), that the scan rate range
is larger at both ends (good Ö 23.5kHz to 85kHz) and that the refresh
rate (nominally 50Hz to 120Hz) range is the same.
8.2
Finally, if you have an extra ú1850 to spend (over and above the
standard-Risc-PC-with-14ö-monitor price) when buying your RiscáPC, you
can consider the Idek MF-8621. This is the matching 21ò model and is
something to save up for! There is also an MT-9121 model mentioned on
page 6 of last monthæs Archive which is ú260 cheaper. It has a slightly
larger dot pitch but the scan rate range is better (23.5Ö92kHz), as are
the frame refresh rates (50Ö160Hz). Altogether a very impressive
sounding monitor.
8.2
I know I Éoughtæ to buy the 21ö model because, in spite of the extra
money, Iæm sure it is a good investment that would see me through into
using my RiscáPC (and later Écomputer typeæ hardware) as a terminal for
the proposed multimedia information super highway. I donæt think I can
raise the cash but this must not deter me from recommending it to you if
you feel that you want to buy the best monitor and one that will last
you through your next three (rather than two) computer upgrades.
8.2
In conclusion
8.2
So Iæve made a start on my new look column. I know that in my quest to
help you develop a strategy for upgrading your system, Iæve concentrated
on monitors this month. I do intend to get around to software soon. As
my examples, I shall choose Wordwise through PipeDreamá2 to PipeDreamá3
to PipeDreamá4 to Fireworkz and also Impression (Junior or II) to
Publisher (or Style). I shall discus how software purchases are future-
proofed. I hope that because I shall concentrate on these few packages
as examples, this wonæt mislead you into believing that only users of
those packages will benefit from reading the article.
8.2
If you have made any of those specific upgrades and want to tell me
about it, my address is that of Abacus Training which you will find at
the back of Archive. Iæd also like to hear from anyone who has an
upgrade strategy all worked out in their minds even (and perhaps
especially) if that doesnæt include any Colton Software product.
8.2
Remember, I shall be looking at document production in general. This
range excludes games, programming and music (amongst other uses).
8.2
Please let me (and our editor) know whether you approve or disapprove of
the broader range which I propose for this column! Or should I revert to
the more focussed remit of the PipeLineZ column?
8.2
For my part, I shall be interested to hear from you in more detail what
you think Édocument productionæ should cover and what it should exclude.
8.2
See you at Acorn World 94!ááAá

Acorns in Business
8.2
Richard Torrens
8.2
I run an electronics manufacturing business in which we use Acorn
computers not only for design work but also for general use. In the
first two articles in this series on using Acorn computers in business,
I will explain how I use PipeDream. I donæt want to go into too much
technical detail or it would become too specific to PipeDream so I will
just explain the type of things I do using PipeDream. If you want exact
details and/or assistance (including copies of files and command files)
my address is at the bottom of the column.
8.2
I will initially declare an interest: I am a fan of PipeDream as it is
such a versatile program. The trouble is that there seems to be a direct
connection between versatility and difficulty of use. Initially,
PipeDream is very simple to use but it has a very long learning curve.
However, PipeDream does just about everything a small business could
want, so you are faced with the choice between a long learning curve on
one package or several shorter learning curves of several packages with
the possibility that they may not cooperate. In any case, much of the
learning is not directly down to the program you are using but is more
about how to organise the business so that it can be done by computer Ö
and this applies to any computerised task.
8.2
If I were running a larger business, I would have several computers: one
would be used as a word processor, another as an accounting computer and
another for stock control and purchasing and so on. I would then have to
employ staff to run the computer programs. This is the way most
businesses work and is one of the reasons they can get away with using
PCs. However, the beauty of the Acorns is that they are far more
integrated: PipeDream is capable of doing a lot of different tasks.
8.2
Between PipeDream and Vector, I can do nearly everything Ö DTP, stock
control, word processing, PCB design and CAD. (Vector is capable of
doing a lot of tasks as I have shown in my earlier articles about
Electronic CAD.) I do, however, use a few other packages for specific
purposes. ArcFax is essential in my business to provide a fax facility
and, since all my documentation is produced on the Acorn, it is very
much easier to fax direct from the computer than to use a dedicated fax
machine Ö and the computer version is also cheaper! (See Richardæs
review of ArcFax on page 47. Ed.)
8.2
I also have a Calligraph laser printer. Well-produced drawings and
properly written instructions present a good, professional appearance,
especially when properly printed on a good laser printer.
8.2
Finally, I use Prophet for my accounts Ö I could do this on PipeDream,
but Prophet has a lot more accounts-specific facilities.
8.2
DTP
8.2
PD4 is not a desktop publishing package but it does pretty well. I use
it for all our brochures and instruction manuals. One day Iæm going to
decide that I want to be a bit more clever and need better facilities,
but for 90% of business publishing PD4 is fine.
8.2
Correspondence
8.2
Part of the business I run is mail order and I get asked a lot of
technical questions. However, as in many businesses, the same technical
questions eventually start to recur, so I have a word-processed file of
answers. Every time a question is asked, if there is a relevant answer
then I copy a slice of the database into a standard letter. If the
question is new, I write a standardised answer into the database.
Initially, the database file grew quite quickly but its growth has now
slowed down. This file is arranged so that it is readable and saleable
as a stand-alone script. This is an idea worth thinking about for anyone
collating technical information.
8.2
Our standard letter has a drawfile letter heading which PD4 uses. It
also does a Élookupæ in my address file so that I only have to enter a
customeræs address once in this file, then either type the customeræs
name into the letter or fill in a reference to the name by pointing to
it in the address file. This method enables me, in a matter of seconds,
to give the customer a detailed and personalised answer to every
question.
8.2
To keep the address files short, I have two: one for enquiries and
another for sales. When an enquiry turns into a sale, I mark the block
in the Enquiry file which contains the customeræs details and move it to
the Sales file. If I sell to a customer whose name isnæt in the Enquiry
file, I know it is new so I send them a price list. If the address stays
in the Enquiry file too long, I transfer it to a Édeadæ file.
8.2
Technical literature
8.2
In Vector, I draw all the items we sell and save them as drawfiles which
PipeDream can use. The technique I use for the drawing is simply to do
them as a full frontal view, life size, by measuring the item and
drawing it as accurately as I can. If the item comes to bits, I draw
each bit separately and assemble them in Vector. I am no draughtsman but
in Vector, I alter the drawing till it looks right and if I draw it
accurately from measurements, life is a lot easier. Also, with Vectoræs
library facility, I only have to draw each item once.
8.2
Invoicing
8.2
We have a complicated price structure because we do both retail trade
and also deal with manufacturers. The reasoning is a bit complex but,
basically, the customer can chose 15%, 10%, 5% or no discount, depending
on how quickly he pays. This did take a little automation but PipeDream
now does all the invoicing with minimum manual intervention.
8.2
I start off with a Sales file into which each order is entered as it is
received. From this, I print out a Sales Sheet for each order. This
wasáquite complicated to do since, although most sales only take up one
line, some take several. To make this file easy to read, I use multiple
entry lines with the sale number blank. So the Sales Sheet has to look
up the next few lines (up to 7) and see if they are numbered as the next
entry Ö if so ignore them.
8.2
When the sale is despatched, I enter the despatched date into the Sales
file and make a one line entry in a file called ÉTo_invoiceæ. All I need
to do is to enter the sale number here: it looks up the Sale file for
info, but I can also enter comments in ÉTo_invoiceæ.
8.2
When I get round to invoicing, I load a file called ÉInvoiceæ which is a
blank form with Élookupsæ everywhere. In one square, I enter the ÉSale
numberæ. Immediately, the file picks up the customer from the Sales file
and looks up his address in the ÉCustomersæ file. It looks up the
products and quantities from the sales file then does a double lookup of
the price: the order may qualify for the 10 off price but many of our
customers have a scheduled order and qualify for the 100 off price. The
blank takes care of all this automatically!
8.2
The invoice number is also looked up automatically (the first number in
the index file which has not been filled in). If the customer is export,
the Customers database has an entry either of his VAT number (for EEC
exports) or simply ÉExportæ. This tells the invoice whether to add VAT
or not and enters öYour VAT number:ò in EEC invoices. The ÉInvoiceæ file
also looks up the Sales file for the the customers order number or
ÉCWOæ. The invoice uses the ÉCWOæ entry to calculate the 15% discount
automatically, otherwise it looks up the item in the database to see if
we give the customer the 10% discount.
8.2
All I have to do is check the file, blank out any unused lines and fill
in the carriage charge. The despatch date is looked up from the sales
file and the invoice date is filled in automatically as ÉTodayæ. When
the invoice looks correct, I pull in another command file which goes
through the invoice, snapshotting the appropriate slots and fossilizing
the invoice. It also removes all intermediate calculations. This command
file also causes the invoice number, date, invoice total and discount to
be written back to the Invoice Numbers file. Save, print and send it.
The whole process involves a minimum of my intervention.
8.2
For regular customers, I have a separate command file Ö one command file
per customer. This fills in all the details relevant for the customer so
that, if they have regular items or have negotiated a bulk price or
special discounts or regular quantities, all this can be automated. It
also saves me having to look up their last invoice to see how much I
charged last time. The whole thing saves me work and reduces my errors.
8.2
Accounts
8.2
I do all the accounting work in Prophet. I could use PipeDream but
Prophet is dedicated and therefore easier to run. The main problem with
PipeDream is that I donæt know the ins and outs of accounting so I let
Prophet do that. Prophetæs manual now includes a section on accounting,
for the beginner but I cannot yet comment as I bought Prophet before the
manual had evolved to this level. Quentin Paine of Apricote Studios has
promised me a copy, so when it arrives, I may return to the subject of
Prophet. Using Apricoteæs !Transfer, I can move data from Prophet into
PipeDream and, since PD4æs Formula line is a writeable icon, I can get
it back to Prophet.
8.2
Next month, I shall conclude by explaining how we use PipeDream for
parts inventory control and raising purchase orders.

Simtec A3010 4Mb RAM Board
8.2
Chris Murray
8.2
I was fed up of seeing the ÉNot Enough Memoryæ message when using some
of the latest applications, so I decided that, before I purchased any
more software, I would upgrade the available RAM on my machine (an
A3010). Currently, it is 2Mb and I wished to increase it to the maximum
of 4Mb. After looking at the various upgrades available, I chose the
Simtec 3Mb RAM expansion card. This has the relatively novel idea of
reusing the existing 1Mb expansion that may (or may not) be already
fitted. I ordered the board over the phone on a Tuesday afternoon, and
the goods came by recorded delivery on Friday morning. Inside the
package was an antistatic box containing a small double-sided PCB about
50╫70mm, which had a handful of components on it plus a flying lead.
Having worked on several PCB inspection lines, I gave it a close
examination with my ╫10 eye glass. This confirmed that it was a well-
manufactured and soldered PCB. The instructions supplied were clear,
concise and very easy to follow.
8.2
Installation
8.2
Opening the computer case and removing the existing 1Mb expansion (two
ZIP chips) was relatively easy. It is easy enough to do this without
unplugging the keyboard edge connector. Refitting the two chips into the
Simtec board was straightforward enough. After adjusting one link inside
the computer, the Simtec board was ready to be fitted.
8.2
At this point you need to be dexterous and brave. The new board sits
into the sockets vacated by the previous RAM chips. There are two rows
of 40 way pins to align and then be pressed very firmly into place.
There is very little room to see what is going on underneath, so great
care must be taken to align pins and sockets correctly. Once the PCB was
fitted and a flying lead plugged in, the case was reassembled. When I
switched on, everything worked perfectly first time (just as it should).
8.2
I now have a lovely 4096Kb total available on the task manager. I feel
much happier now about purchasing software, knowing that there is plenty
of memory available. I have increased the font cache (suggested in
Archive 7.5 p35 & 50). This give a much improved screen update when
using fonts. The computer has been used every day (often for several
hours at a time) for the last three weeks without any problems. The
whole installation took only 30 minutes which included unpacking and
reading the instructions.
8.2
Conclusion
8.2
Having worked in quality assurance for a number of years and seen many
electronic manufacturing companies, I must say that Simtec have produced
an excellent piece of hardware here that does exactly what it is
supposed to and at a very reasonable price. I have no hesitation in
thoroughly recommending this product.

Advanced Basic Ö OLE Again
8.2
Paul Hobbs
8.2
Last month, I mentioned that I had found a PD library that had a module
to handle OLE. However, on receiving it, I discovered that it appeared
to be the Computer Concepts OLE module and documentation which I had
been informed was only for use by Computer Conceptsæ applications. I
will attempt to clarify the situation but it looks as though we will
have to stick with the scheme outlined last month Ö unless anybody has
written a module which really is PD.
8.2
Impulse II
8.2
One Computer Concepts module that is PD is ImpulseII which is designed
to make inter-application communications easier. Despite being heavily
featured by at least one Archimedes magazine a long, long time ago, it
does not seem to have become a standard in the way that Computer
Concepts hoped, its main use being handling mail merging for Impression.
One reason for its lack of popularity is probably the available
documentation which, whilst being comprehensive, is somewhat confusing.
8.2
Should you want to send data between applications (perhaps for debugging
purposes as mentioned in an earlier column) it seems to make sense to
use this existing module as it handles the building of wimp messages for
you and generally makes things easier.
8.2
The way it works is that a ÉMethod Tableæ is built in memory which
contains the command words and any command parameters recognised by your
program. This ÉMethod Tableæ is passed to the Impulse module directly
after the call to Wimp_Poll so that Impulse can decode any incoming
Impulse messages.
8.2
If enough ÉMethodsæ are supported by your application it would be
possible to allow another application to control all aspects of its
operation. However, a more likely scenario would be to allow your
application to supply a service to other applications. For example, a
graph drawing program could accept a list of values and return the graph
as a drawfile.
8.2
The purpose of the following code is to make an application respond to
the Impulse commands Éopenwinæ and Éclosewinæ for demonstration
purposes. Note that I have overcome my fear of global variables after
reading ÉCode Completeæ by Steve McConnell Ö I have adopted the
convention that global constants have names in capital letters.

The monthly disc contains the full ImpulseII documentation and some
example programs. In order to test the Impulse demo application, it is
necessary to have a program that can send Impulse commands as the above
code only handles the receiving of commands. Luckily, Computer Concepts
supply the rather mis-named !Insight application which allows the
sending of Impulse commands and the display of Impulse replies. (I say
Émis-namedæ because it is not written in Basic and so provides no
insight into how to use the module!) Unfortunately, it only allows the
sending of commands, not requests that expect a reply, so next month,
all being well, Iæll present an application to do this.
8.2
A couple of points to note about !Insight: you quit it with an <adjust>
click on the iconbar icon (or via the Task Manager) and Impulse commands
are broadcast to all applications unless an ÉObject Nameæ is given in
the command. Typical command strings would be:
8.2
:ImpDemo OpenWin
8.2
(command ÉOpenWinæ sent to application ÉImpDemoæ)
8.2
:OpenWin
8.2
(command ÉOpenWinæ sent to all applications)
8.2
The ÉObject Nameæ is usually the name passed to Impulse_Initialise, but
it could include a document name, for example:
8.2
:Impression.MyDoc OpenDoc
8.2
(command ÉOpendocæ sent to document ÉMyDocæ in application ÉImpressionæ)
8.2
:Impression.MyDoc OpenDoc ö10 10 500 -600ò (as above, but open document
at specified coordinates)
8.2
In these cases, PROCImpulse_Command() would be passed the unresolved
part of the object name (ÉMyDocæ) and it is up to your application to
decode the object name appropriately. In practice, the ÉObject Namesæ
and ÉParametersæ can be as complicated as you want.
8.2
Owners of Impression Style or Publisher are provided with a couple of
Basic applications which provide some more clues about how it all works.
8.2
As this subject is quite complex, weæll leave it there for this month
before I fill the whole magazine.

Outline fonts in menus
8.2
I have had a letter from Michael Carter who asks if anyone has found a
way of emulating the Risc PC feature of forcing the system to use an
outline fonts in menus. The PD application !DeskFonts is OK but doesnæt
handle menus correctly in that keyboard shortcuts are not displayed
right aligned.
8.2
This feature is of importance to software authors who do not have access
to a Risc PC for testing exactly how their application looks when
outline fonts are in use. If anyone has found a solution to this
problem, we would certainly like to know.
8.2
If you have any suggestions for topics that could be covered in future
issues, I would be pleased to hear from you. My address is Paul Hobbs,

ArcFax Ö A Software Fax Facility
8.2
Richard Torrens
8.2
These days, a fax facility is almost a necessity for running a business.
When people asked for our fax number, they were most put out to find
that we didnæt have one Ö so we invested in David Pillingæs ArcFax and
bought ourselvesáa fax modem. Now when people ring to ask what our fax
number is, some are a little put out that we receive faxes on a voice
line and they are often surprised when we say that the faxes come
straight into our computer. Although computers are so universally used,
few business users actually seem to know anything about them and the
tricks we Acorn users take for granted can be very impressive to the
average customer.
8.2
When I first thought of reviewing ArcFax, I wondered if I was going to
be able to say enough about it. It just sits on my iconbar waiting for
me to use it. I use it to send or receive a fax and then forget about it
again.
8.2
What is a computer fax?
8.2
The Acorn computer prints by sending to the printer a graphic image of
the page which is made up as a series of dots. Normally, an electronic
representation of these dots is sent up a cable to the printer. The fax
modem can be thought of as a Éprinteræ which turns these dots into
sounds which can be sent down the telephone line to a remote receiver.
The receiver may be another computer with a fax modem or an actual fax
machine which turns the sounds into dots on a piece of fax paper. So a
computer fitted with a fax modem and ArcFax can send and receive faxes
to and from any fax machine in the world whether it is a stand-alone fax
or an IBM running a fax program or, of course, another Acorn. However,
ArcFax is much more clever than this and has a lot more facilities.
8.2
Fax modems
8.2
The fax modem we use is a small box about the size of my hand. It plugs
via one cable into the computeræs serial port and another into the
telephone. Then you forget it. Mine sits behind the telephone out of
sight and out of mind, gathering dust.
8.2
David Pillingæs software is growing. The version I have is 1.11 but its
abilities are limited by the available modems. Modems are now appearing
which can digitise speech so, if you have one of these fitted, you can
use your computer and ArcFax to answer the telephone when you are out!
It can replay a recorded message and will record incoming messages
exactly like an answering machine. If the incoming call is a fax, the
modem will recognise the fact and receive the fax automatically.
8.2
Comms
8.2
A fax modem can, of course, be used for standard comms purposes just
like any other modem. ArcFax is not a comms package so, for Comms, you
will need other software, but there is plenty of this around Ö including
Hearsay from Beebug Ltd, also written by David Pilling.
8.2
Receiving a fax
8.2
If you are lucky enough to have a class 8 modem, ArcFax will listen in
to your telephone calls: if it detects a fax tone, it will automatically
receive it. ArcFax can be configured to automatically receive (or
ignore) voice, fax and data. However, we have a simpler modem which
doesnæt recognise voice so we answer calls manually. We have no
difficulty in knowing when the call is a fax: some faxes send tones to
initiate the transmission but other fax machines wait until the called
machine sends tones to them. The first are easy to recognise but we soon
got used to the mechanical sounding deadness of a fax machine waiting
for us to respond. In either case, we just click on the fax icon and a
window appears. In this window is a ÉReceiveæ button. One click on this
and ArcFax takes over. Of course, if we know a fax is about to arrive
(or if we had a separate line for the fax) then we would configure
ArcFax to automatically answer all the calls. With a shared line, we
like to leave ArcFax on manual.
8.2
During reception, the window shows the status of the fax, including the
calleræs identification. Once the fax has been received, a tick appears
and you can open the RXBatch window and view the received fax. If you
want, you can print it straight out to the laser printer. ArcFax also
allows you to process the fax, save parts of it, etc.
8.2
Sending a fax
8.2
ArcFax uses Acornæs standard RISCáOS printer driver just the same as any
other printer. It redirects the output to disc, compressing it en route.
Once printing to disc has been done, you can view the resultant fax file
or send it straight out. However, ArcFax can also do all the sending
automatically for you. It has a telephone directory and you can tell it
to send to any entry or a new number or even a group of entries, so you
can send your fax off to twenty people if you wish Ö the ultimate mail
shot? Yes, unfortunately, junk faxes are catching on, but ArcFax can
even deal with a lot of these.
8.2
Directory
8.2
For me, this is one of ArcFaxæs most useful features. There is a full
directory with a scrollable index page. Open the directory, scroll down
to the name you want and click <select> and ArcFax dials the voice
telephone number. ArcFax does all our dialling for us. No more
misdialled numbers and no more hunting for the telephone number.
8.2
Click on the name with <adjust> and a window opens for the entry showing
the personæs full name and address. There are other options here such as
ÉBaræ Ö if this is ticked and your fax and phone support caller-
identification, the caller is barred from your system. I know several
double-glazing companies I would wish to put on this list Ö but I donæt
have the right type of modem. Another option is ÉBlockæ which works on
Fax idæs only, so is useful if you want to block junk faxes from a
particular fax machine.
8.2
Another very useful feature is that ArcFaxæs directory supports drag and
drop Ö you drag the directoryæs name entry into a wordprocessor window
(such as PipeDream 4) and the whole name and address is dropped at the
cursor. I could use this a lot more Ö except that most of my
correspondence is one off and if I used ArcFax for my regulars, I would
then be using two different systems together Ö always a cause of
confusion.
8.2
Automatic sending
8.2
ArcFax has facilities for automatically sending a fax. If you put the
words, for instance, {fred } in the document you are printing via the
fax printer driver, ArcFax will pick this up and automatically look up
the entry ÉFredæ in its directory. Out goes the fax automatically with
no further ado.
8.2
There are other ÉEmbedded commandsæ which ArcFax will recognise
including {xyz } (the fax will be saved as Éxyzæ) and {date/time } which
will start ArcFaxæs timed sending facility. There is a small problem
with embedded commands: there is no way of cutting them out of the
document in which they are embedded so they are sent out in the finished
fax. However most wordprocessors can use some trick (such as white text
on a white background) to make sure the commands donæt show up.
PipeDream doesnæt support coloured text, so we simply use 1 point text
and position it so that it is printed under a black part of our logo.
One point text would, in any case, show up looking like line noise and
would be unreadable. (If you use Impression, you can position these
commands within the print border making sure that you include some hard
spaces in extra large text so that they, invisibly, stick out into the
printable area thus forcing Impression to render the whole line
including your commands which ArcFax then picks up. Ed.)
8.2
Timed sending
8.2
A lot of our customers are overseas and so it can be useful to send the
fax at a particular time when the recipient is at work Ö or when the
rates are cheapest. ArcFax has a facility to delay transmission of the
fax until a stated day and time by using the {date/time } embedded
command or you can delay the sending manually.
8.2
Save money by using Mercury
8.2
ArcFax also allows you to put a prefix in front of any or all phone
numbers. This can be the Mercury initiation number, 131, followed by
your pin number. Once again, after the initial set-up, this is
transparent to the user and all calls, where appropriate, go via Mercury
thereby saving you money.
8.2
Scanned images
8.2
ArcFax now supports Twain interface to control scanners. I donæt have
one, as all the information I wish to send is computer-generated, so I
canæt tell you much about this. But, again, there is not much to it. You
just click on Éselect sourceæ (if you are using more than one scanner!)
and then on ÉScanæ. Then you just send the scanned image as a fax.
8.2
Other features
8.2
ArcFax is stuffed full of other features and David Pilling has thought a
lot about extra things that he could add depending on what would be most
useful to the users. ArcFax is very much a continuously developing
product.
8.2
Gripes?
8.2
No review would be complete without a few gripes. Let me see if I can
think of any... The manual has no index. Mind you, it is quite readable
and covers just about everything I need. An index would be nice, but I
can live without it.
8.2
The program is getting a bit large. It takes 512Kb and, if you use it
for receiving faxes, it isnæt the sort of program you can load up only
when you need it. My 4Mb of memory is getting a bit small, especially
since I have also upgraded to PipeDream 4.
8.2
I did have trouble when I first bought the modem: we were on pulse-
dialling and the modem didnæt correctly recognise the tones, but since
weæve changed to tone-dialling, I have had no trouble and the new manual
does include hints about pulse-dialling exchanges.
8.2
Since writing the above Ö I have changed to a Risc PC. I am happy to
report that ArcFax performs perfectly with this but I did have to phone
David as one module needed updating. All I did was switch ArcFax to
receive data and the new module came straight down the telephone from
David. There was also a funny five minutes where I couldnæt get the
printer driver working with the RISCáOS 3.5 driver. When I read the
ArcFax manual, I realised that hadnæt installed it correctly.
8.2
So, no, I canæt really find any serious gripes!
8.2
Summary
8.2
If you need a modem: get a fax modem. If you have such a modem then,
even if you donæt use the fax facility, ArcFax is worth getting just as
a telephone directory. If you need a fax and have an Acorn machine, get
a fax modem and ArcFax. If you think you need a dedicated fax, wouldnæt
it be worth spending the money on a scanner instead? That way, you get
the best of all worlds.
8.2
ArcFax costs ú35 from David Pilling or ú33 through Archive.ááAá
8.2
This article didnæt come in until after we had set up our special offer
last month of a Worldport fax modem with a free copy of ArcFax. The
offer was only to be for two months but we will try to extend it a
further month to allow subscribers the opportunity to make a more
informed decision in the light of Richardæs article. Ed.
8.2
Small Ads
8.2
(Small ads for Acorn computers and related products are free for
subscribers but we reserve the right to publish all, part or none of the
material you send, as we think fit. i.e. some people donæt know what
Ésmallæ means and there are certain things, as you can imagine, that we
would not be prepared to advertise as a matter of principle. Sending
small ads (especially long ones!) on disc is helpful but not essential.

The ARM Club
8.2
Andrew Rawnsley
8.2
Just recently, a wide variety of user groups that have sprung up to
support owners of ARM-based computers. Arguably one of the most
significant of these clubs is the ARM Club which has been in existence
for some time now, but has received little public acknowledgement for
its work. Since the Club provides a service that would benefit Archive
subscribers, I feel that readers may be interested in learning more
about it.
8.2
Advertising?
8.2
Before you jump to any conclusions and decide that I must be an ARM Club
committee member trying to boost the groupæs publicity, I should make it
clear that Iæm certainly not. Only six months ago, my attitude was as
apathetic as that of many others Ö I knew the Club existed but it seemed
rather remote and of little interest to me. How wrong I was....
8.2
The service provided
8.2
The ARM Club could almost be classed as a public service Ö offering a
great deal for a very reasonable price Ö just ú10 per year.
8.2
At its minimum, the Club offers a quarterly magazine known as Eureka
which comprises approximately 70 pages of news, reviews and special
offers. Members of the Club, and hence readers of the magazine, are
actively encouraged to get involved Ö for example, writing articles,
attending committee meetings and helping in the organisation of local
shows.
8.2
In addition to all of the above, the club runs an extensive PD library,
at the bargain price of ú1 per disc, and recent offers included a Ébuy
one, get one freeæ scheme.
8.2
The main problem with the magazine is that its layout gives away the
Clubæs user-group based feel. Unlike the professional approach that we
are used to in Archive and the rest of the Acorn press, Eureka can have
articles running down one column of a page, continuing four pages later,
again in just one column, and then finishing two pages further on.
Whilst this may be a rather over-the-top example, Iæm sitting here
looking at another article that does just that. Perhaps this is not a
major criticism, but Archiveæs column balancing approach within an
article makes each one much more readable.
8.2
There are regular Club meetings for members in the south of the country,
and lists are distributed of membersæ particular fields of interest
(unless the member doesnæt wish to be included), so if you are
interested in MIDI on Acorn machines, you can get in contact with other
users in your area who are like-minded.
8.2
Shows?
8.2
The ARM Club encourages Open Days with leading players in the Acorn
software and hardware market exhibiting Ö organised by members! Indeed,
I was approached at the BAU Spring Show and asked if I would be
interested in helping in to organise a small show / open day in the
NorthWest.
8.2
This gives the opportunity for members to meet representatives from
major Acorn companies and partake of the special offers available to ARM
Club members Ö quite exciting!
8.2
Other benefits
8.2
Not being a dealership, the ARM Club does not sell Acorn-based products
to members (PD excluded) but the Club negotiates deals with various
software houses allowing members to purchase software direct from the
company at discounted prices.
8.2
Conclusions
8.2
I suspect that my conclusions will by now be obvious! The ARM Club has a
lot to offer and I for one will be renewing my subscription when the
time comes, in the sure knowledge that it is money well spent.
8.2
The ARM Club can be contacted at: Freepost ND 6573, London N12 0BR.
Phone/fax: [phone].
8.2
If you should want to contact me either for further information, or if
youære in the NorthWest, for local details, Iæm available on: phone
01925-755043 (outside office hours) or fax [phone].ááAá

Outline Font Design Made Simple
8.2
Christopher Jarman
8.2
One of the reasons I bought a computer in the first place was my
interest in handwriting and lettering. Thanks to Roger Spooneræs
excellent help through his articles in Archive and his generous advice
over the phone, and also thanks to Dave McCartney of Datafile, I have
been able to design two or three fonts myself and to put them to work.
(The Jarman font for use in handwriting copy sheets was distributed free
on the Archive 7.5 monthly disc.)
8.2
Tools for the job
8.2
The basic tool for this job is the program !FontEd. It is obtainable
from Acorn and various PD sources, and is said to be quite complicated
to use. Its manual on textfile is certainly quite a good example of how
to confuse a reader. However, perseverance pays, and although I still do
not know what some of the items on the menus are for, I have discovered
how to design and edit a font! This is fairly intuitive Ö but much
easier using Rogeræs guides! (Archive 5.12 p45, 6.1 p75, 6.2 p17, 6.4
p45 & 6.5 p55)
8.2
The biggest breakthrough, however, has come with David Pillingæs !D2Font
application, part of his program !Trace obtainable direct from him or
through Archive. This allows you to draw or design letters of your own;
either in Draw or in any application that saves in drawfile format, then
to put them one by one into the !D2Font matrix where they will type out
from the keyboard. It is not quite as simple as that, but it is fairly
easy once you have become confident in ironing out the little problems
caused by your own inadequate drawings! In fact, it is essential to put
the !D2Font results into !FontEd first for editing and spacing, before
they can be successfully used as an outline font.
8.2
The best way to explain how to do it, is to take you through the design
of, say, three letters step by step.
8.2
This is the lower case abc of an alphabet designed as an informal font
which was meant to look as if it was cut out of paper. I call it
ÉCutfontæ. It actually only took about an hour to do the whole alphabet.
It was deliberately done hurriedly!
8.2
These letters were drawn in outline using the straight line segment tool
in Draw. With the grid showing, the x height of the letters is 4cms. For
a complete alphabet it will be necessary to use several drawfiles
containing groups of four or five letters. If you are going to design
capital letters, punctuation and numbers as well, it helps to label them
accurately as you save each file.
8.2
As a rough guide, for most alphabets, make your ascenders (bdhl etc)
around half as tall again as the small letters and make the capitals
about the same height as the ascenders. The small Étæ is lower than the
others, with its cross-bar at the height of the small letters. Look at
some standard fonts to get the proportions, as these are the most
frequent errors in lettering design. Numbers should again be about the
same height as the capitals. At this stage, you should aim to draw just
a really rough alphabet which, although untidy and perhaps out of
proportion, is at least your own unique font.
8.2
Enter D2Font...
8.2
Load !D2Font onto the iconbar and click to show the grid. In Draw, there
is a facility for saving only selected parts of the page. Select letter
Éaæ from your design either using the menu or <shift-f3> and drag it
into the pale grey square marked Éaæ in the grid. (See on previous
page.)
8.2
 It should then appear as a tiny letter Éaæ. By double clicking on this
small Éaæ in a square, it will appear large sized for your inspection.
8.2
At this stage, you may be unlucky and find that the letter is
incomplete, or that the centre of it is blacked out. Do not worry. As
long as there is something in the box, FontEd will come to your rescue.
8.2
Continue to select each letter and drag and drop them one by one into
the relevant grid boxes in D2Font. As a tryout, I would suggest using
only two or three letters first, and see how you get on with them before
attempting the whole alphabet. When you have everything you wish
transferred, select ÉSave Fontæ (there is no need to select Save D2
Font) and give your font a name. Put it into a convenient directory. It
should now have its own folder looking like any other outline font in
your collection, even though, at this stage, you may only be trying out
three letters.
8.2
Using FontEd
8.2
Next load FontEd onto the iconbar. Open your newly named font directory
and drag the ÉOutlinesæ file down to the FontEd icon. You will see
another grid appear just like the one from D2Font as follows...
8.2
However, when you double click on a letter in this application, it will
not only appear larger but will be in outline form rather like an object
in Draw or Artworks. It will have green dots as movable points, and
handles for curves as required. At this point, some letters may not
appear filled in black in their small squares. This is only because the
outlines are not joined upásomewhere. So you have to inspect each green
dot to see if it is really two green dots which are not joined. When you
find them, use <adjust> to move one over the other, just as in Artworks.
Clicking <menu> over the enlarged window for a letter will give you an
option called ÉFull Charæ. This will give you an enlarged black picture
of the letter you have been working on.
8.2
By using <select> to make lines and <adjust> to move them, you can re-
design, mend and manipulate the letters as much as you like. For full
details, refer to the three Fonts Workshops articles in Archives 5.12,
6.1 and 6.2.
8.2
When you have altered all your letters to your satisfaction and arranged
their widths to suit, do not forget to type in a width for the square
marked Éspæ which sets the spaces between letters.
8.2
To do this, you double click on Éspæ, then click <menu> in the large
blank square. select Éwidthæ and move to the right, type in 400 (as a
start) and see how it looks. Later, you can try greater or lesser width
spaces, after trying out the font in your word processor or in Draw.
8.2
When you are satisfied with any alteration, click <menu> over the
background matrix and click ÉSaveæ.
8.2
To try out your new font, discard FontEd and drag the font file into
your usual Fonts collection. Once installed, any further editing using
!FontEd will take place automatically wherever you have put the file.
8.2
The results
8.2
This is Cutfont. It was put together in about an hour using the method
described. Capital letters and more careful spacing were done later.
8.2
THIS IS TOONFONT, DESIGNED IN DRAW, THE SAME WAY AS CUTFONT. IT WAS
DESIGNED BY MIKE FLANAGAN, THE CARTOONIST, TO GO IN THE BUBBLES OF HIS
CARTOON CHARACTERS.
8.2
This is a font called Wyke which took very much longer to design and is
meant to look like pen lettering.
8.2
Cutfont and Wyke are not commercially viable complete fonts but you may
try them out on this monthæs program disc.
8.2
The Trace disc (which also contains D2Font) is obtainable from David
Pilling price ú10 inclusive or through Archive at the same price.ááAá

Puzzle Corner
8.2
Colin Singleton
8.2
(In response to a request a few months ago, Colin has offered to provide
us with some more puzzles out of his huge repertoire. Ed.)
8.2
What I will try to do is to provide two puzzles each month. There will
be (small!) prizes for the first three correct entries for each puzzle
drawn out of the bag on the final date for entries which is Friday 11th
November. That gives you less than a month but it means Iæll be able to
publish the answers in the magazine that you will receive the week after
the deadline Ö that should keep the interest going, even if you werenæt
able to make an entry. Iæll give the names of prize winners in the
following issue. You will know you have won before then because you will
(if weære efficient! Ed.) have received your prizes before then but we
feel you should get some public acclaim as well.
8.2
Anyway, here are the first two puzzles...
8.2
(1) This is 1994
8.2
You may have come across the Éfour foursæ problem in which you are asked
to find a way to form each positive integer from one. As far as you
could, each should be expressed using four fours with any standard
mathematical symbols.  For example, 76 = 4!/îÅ4 + 4┌4. Some of the
expressions became very involved. (Let me try... 1 = 4*4 / 4 / 4á andá 2
= 4*4 / (4+4)á and then 3 = (4+4+4) / 4.á Thatæs my limit! Ed.)
8.2
You will not need any obscure functions for this puzzle, the solution
can be given as a single expression in the Basic programming language,
or on one of the better scientific pocket calculators. All you have to
do is form the number 1994 as an expression using, not four fours, but
the digits 1á9á9á4 in that order with suitable mathematical symbols.
8.2
(2) Conversations
8.2
Alan, Bill, Chris, Dave, Eric and Fred have gone to their local hostelry
for a quiet drink or two. It is, of course, likely that they will engage
in conversation in groups. They might all form one group, or they might
split into smaller groups not necessarily the same size. Some, or all,
may remain alone, and presumably silent.
8.2
In how many different ways might the six friends form conversational
groups?
8.2
Feedback
8.2
If you have any comments or suggestions to do with Puzzle Corner, write
to me at 41 St Quentin Drive, Sheffield, S17 4PN but send your answers
to the puzzles to Paul at the Archive address by 11th November.ááAá

Å  Acorn sharesáÖáI have some money to go towards buying a RiscáPC but
only about half of what I need. Iæd like therefore to invest that money
in Acorn shares and then in 2-3 years time when the next generation of
amazing Acorn computers appears, Iæll be able to buy one as the shares
will have doubled in value Ö well, thatæs the theory. The trouble is
that I live in France. Can anyone help me to buy them directly from a UK
broker as the procedure for doing that from France is far from easy?á

8.2
Å  Help with Acorns Ö Is there anybody within a 50 mile radius of Biggar
in Lanarkshire, who is conversant with Acorn machines and may be able to
lend a helping hand to me with the use of my system? My main uses are
with Impression and Artworks. Please contact Anna McCosh on 01899-20221

Å  PC file formatsáÖáAs a total stranger to the PC world, I am having
trouble examining images, sound samples, etc, using ChangeFSI,
Translator, AudioWorks etc. The problem is that I am never quite sure
what all those file types are that appear after the / in a DOS file
name. Is there a list that I can refer to? If not, is there someone who
can compile such a list and maybe we can have it published in Archive so
that I can refer to it. All I want is something along the line of WAV-
Sound Sample, BMP- Graphic file, so that I know which Acorn program to
try and load it into!á Paul Hooper, Norfolk.
8.2
Iæm not sure if this is the sort of information that Simon Coulthurst as
Risc-DOS Column editor might want to collate, but then Jim Nottingham is
doing some work on the interchange of different file formats, so perhaps
he might want to do it. Well, just send in your ideas, comments, etc to
the Archive office and weæll see who wants to deal with it! Ed.

Å  Star NL10 graphics printing Ö Is anyone using a Star NL10 printer to
print desktop fonts and graphics? I am using an A5000 with RISC OS 3.1,
and the Acorn LX80 printer driver. Printing from Draw, the graphics
start printing at the bottom of a sheet and spill onto the next one.
Text in Impression doesnæt print at all unless I use a large point size,
and there are still problems in that there are gaps in the printing. Any
help would be appreciated. Contact JáFell, 26 Gladiator Green, Castle

SCSI Card Compatibility
8.2
Jim Nottingham
8.2
In Archive 7.12 p53, I invited readers to let me have details of their
SCSI cards and SCSI devices with a view to making the data available to
readers, hopefully to help future purchasers avoid problem areas. By
coincidence, and for the same reason, Keith Hodge asked for the same
data two pages later. He and I have pooled the responses and this
article is by way of an initial report. Anything in double-quotes is
cribbed straight from readersæ letters.
8.2
Some twenty readers have responded to date; sincere thanks to you all
for making the effort to send such detailed and helpful replies. That
said, there must be far more than twenty readers with SCSI systems, so
how about more replies folks? The more data for the database, the more
useful it will be. Only two of the SCSI interface manufacturers
responded to my letters so we are rather short of details there.
Fortunately, a couple of third-parties have come up with some very
valuable data; many thanks to David Pilling and Dave Webb (NCS).
8.2
The database
8.2
The information received to date is shown on the table (presentation
courtesy of TableMate 2). The data has been accepted Éas isæ and is
given in good faith but, clearly, neither I nor the publishers of
Archive can accept any responsibility for its accuracy or use. Caveat
emptor and all that. If anyone spots errors, please do let me have
details. If and when further data becomes available, this will be added
and the survey re-issued as appropriate.
8.2
In the body of the table, a single or multiple tick indicates one or
more reader-reports of successful operation of the SCSI device when
connected to the listed interface. Similarly, a cross indicates a
reported incompatibility. Where an asterisk is added, this indicates a
Égrey areaæ where, typically, success was achieved only after one or
more problems were ironed out. Unfortunately, these details are far too
extensive to include in this survey but, should anyone be considering
moving into a combination of card/device with an asterisk against it,
and would like to receive details of the relevant reader-report, please
drop me a line with a stamped, addressed envelope and you shall have a
photocopy by return. The same goes for any other information with which
I may be able to help.
8.2
The model of host computer used does not appear to have any bearing on
compatibility so details are not included. However, it should be borne
in mind that, when converting to a Risc PC for example, it may be
advisable or even essential to have your SCSI interface upgraded to take
advantage of latest improvements. Generally, this will involve buying an
upgrade kit and often entails swapping a ROM on the SCSI card.
8.2
The SCSI cards
8.2
The table lists all known SCSI interface cards for Acorn computers,
although one grey area is whether some of the cards are still available.
For example, it is known that supplies of the State Machine Eco card are
almost exhausted and will not be resurrected. The Cumana SCSI II card is
a recent entrant and Iæm not sure about availability. Castle Technology
have recently taken over the marketing and support of the Lindis/
Lingenuity SCSI cards and up-to-date software is available for all
versions of the interface.  They plan to release a new 8/16-bit card at
Acorn World 94.
8.2
Hardware and software version numbers are the most recent reported.
There seems to be near-equality in the version of CDFS used on the
various interfaces. The reason for this is that the software is included
under licence from Acorn.
8.2
With the exception of the Atomwide and State Machine Eco cards, all
interfaces have a socket on the card for an internal device and a second
socket on the rear panel for connection of external SCSI device(s).
There is only one reported limitation on choice of podule slot; in the
Risc PC, the Morley cards should be inserted in Slot 1. Following
installation, the Morley and Oak cards have to be configured so they
know which slot they are in, which devices are attached, and so on; this
also applies if you move the card from one slot to another.
8.2
Both variants of the externally-mounted Atomwide SCSI interface (with
and without printer socket) plug into the bi-directional printer port of
A5000s and the Risc PC and have a single socket for SCSI devices. They
are compatible with Computer Conceptsæ TurboDrivers and the dreaded
dongles.
8.2
The State Machine Eco card is a most interesting option. It is a small
module which plugs into the Econet socket of the A300/A400/A540/A3000/
A5000 computers (for safetyæs sake, early A3000 owners are advised to
have it fitted by a dealer Ö something to do with the unprotected power
supply). The card has a single 50-pin edge-connector for an internal
SCSI device, although it would be possible to take a flying lead through
the computer case for connecting devices externally. Apart from the
advantage of not taking up a podule slot, it appears the card is
remarkably compatible with all manner of devices including CD-ROMs and
scanners. The card is actually stamped ÉFloptical Interfaceæ. Software
comes on disc and there has been mention of running CDFS with Kodak
PhotoCD support. Another great advantage is the cost Ö ú35 + VAT!
Unfortunately, supplies are running out so you may need to get in quick.
8.2
Hard disc drives
8.2
Maximum free memory on storage devices, including hard discs, is usually
5-9% less than the nominal capacity of the device. The data listed in
the table under ÉCapacityæ gives an indication of the lower figure,
where known. There is some confusion over the Rodime drive model numbers
and capacity so, if you move into that area, do double-check you are
getting what you want.
8.2
Apart from the two tabulated incompatibilities with the Quantum 105S
drive, there were no reported problems in getting hard disc drives to
work reliably, whether mounted internally or externally. There were two
reports of drive failure, both Quantum, model(s) not known.
8.2
Use of fan quieteners was questioned in relation to whether hard disc
drives were put at risk of overheating. Two readers commented that
fitting a fan quietener had little beneficial effect as it turned out
the drive was noisier than the fan!
8.2
Cartridge drives
8.2
The flexibility and potentially unlimited capacity of removable
cartridge drives is making them increasingly popular. There was only one
reported difficulty in getting a drive to run (a duff drive, replaced by
NCS). Over a year ago, Oak said their card was not recommended for
SyQuest drives but Iæm not sure if this is still the case.
8.2
Most drive owners reported that, unless a cartridge is inserted and
running in the Syquest drive when the computer is shut down (*Shutdown
or <shift-ctrl-f12>), the computer will hang up with error messages
depending on the SCSI interface. Two readers readily admitted that,
because of this shortfall, they no longer shut down their computers in
the approved manner. Does anyone have any advice on this problem? Is
this OK or detrimental to the health of hard discs? The Acorn card
throws up an error message but will allow shutdown.
8.2
Floptical drives
8.2
Although three readers reported successful operation of floptical
drives, there were quite a few problems to be resolved and, with
questions being asked about follow-up support, it seems to be a dodgy
area. ö...(Installing a floptical) was probably a mistake. I should have
saved up for a Syquest drive for backing-up purposesò.
8.2
Tape streamers
8.2
There was only one reported use and there were problems with tape
capacity and in setting it up. öThis will soon be replaced with a
removable ... driveò, so he canæt be too happy with it.
8.2
CD-ROM drives
8.2
There were few significant problems setting up CD-ROM drives. The Sony
CDU-8003A is actually an Apple (who?) CD300 and needs a patch, available
from Acorn dealers including NCS.
8.2
As reported recently in Products Available (7.10 p4), Morley supply a
special driver to use multisession PhotoCD with the Toshiba drives. This
is now supplied with Morley cards but is also available as an upgrade on
disc for other interfaces and earlier Morley cards.
8.2
I had a problem recently when running audio CDs in a Toshiba drive
connected to a Morley cached card (intermittent stopping). If you get
this problem, contact Morley who have a replacement chip available. Two
readers with Morley cards mentioned their computers crashed if they
clicked on a CD-drive icon and there was no disc in the drive (the Acorn
card gives a ÉDrive emptyæ error).
8.2
Scanners
8.2
This is a fast-moving area with falling prices and increasing
availability of potentially suitable scanners. However, there are
numerous reports of certain units being öpickyò as to which interfaces
they will run from, or otherwise being less than stable.
8.2
Irlam recommend the Morley cards for the Epson scanners. The Acorn card
will also run the Model 8000 and Ö with tweaking Ö can be made to run
the 6500, but this is not advisable. Reportedly, the Hewlett-Packard
scanners are not reliable on the Morley cards (öit ... seems an
intermittent problem Ö if you switch the system on and off enough times,
then eventually it worksò). Integrex recommend only the Cumana card for
their CS300 while the Aries Relisys scanners from Watford Electronics
will operate only with the Cumana SCSI II interface.
8.2
Installation
8.2
One brave soul successfully converted an external device to internal use
by removing the gubbins and installing it in a Risc PC. The only
problems reported were finding the power cable (hidden under the floppy
drive), getting a suitable data cable and, as the device finished up
without terminators, having to make sure it was in the middle of the
SCSI daisy-chain. Iæm not sure I would want to ÉRiscæ doing this Ö
wouldnæt the device/computer warranties be affected?
8.2
Connections
8.2
Tying everything together seems to cause no end of problems and
confusion, mainly due to there being little standardisation of
connectors and, sometimes, inappropriate names being used to identify
them.
8.2
All internal interfaces have an oblong, 50-pin, edge-connector plug
mounted on the card itself, normally used for connecting an internal
device, commonly by a ribbon cable terminated by a 50-pin header socket.
(The term ÉIDCæ Ö insulation displacement connector Ö is often used but,
strictly speaking, this refers to the method used to fix ribbon cable to
the plug or socket, a clever crimping tool being used to avoid having to
solder individual connections.)
8.2
External connectors can be one of three types; a 50-pin edge-connector
as described above, a 25-pin D-type socket or a 50-pin Centronics socket
(rather like a printer socket but bigger Ö called ÉAmphenolæ by NCS).
There is an odd man out Ö the HCCS Ultimate micropodule has a
proprietary connector but I understand is supplied with an adaptor lead
with a Centronics plug attached.
8.2
External boxes or devices will have a connector which can be any of the
three main types mentioned above, although Centronics is probably the
most common these days. Many external devices will have two sockets,
allowing for easy connection in the middle of a SCSI daisy-chain. The
actual cables for external connection are normally of two types; a 25/
50-way ribbon cable, usually with IDC connections, or a heavy-duty 1cm
diameter screened cable. Clearly, with this range of different
connectors and cables, you could easily finish up with the wrong type.
NCS and others can supply cables to suit but more than one reader
reported having to have a Éspecialæ made up or resorted to DIY.
8.2
Device ident & termination
8.2
There seems to be considerable confusion about device identification and
termination. This is not altogether surprising as, in my view, interface
and device manufacturers make the whole thing unnecessarily complex,
whilst user-guides are often over-technical with sloppy editing. The
outcome is that many people reported problems, not all of which were
sorted out by the suppliers. Some admit to simply ignoring things like
correct termination (öIf it works, why fix it?ò).
8.2
Make no mistake, if you do not correctly terminate your SCSI system, you
run the risk of corrupting data or even damaging your SCSI card and
devices (Iæve seen two cards Éblownæ on PCs). The subject is outside the
scope of this survey but Dave Webb at NCS has sent me a copy of a very
well-written and informative guide they send to customers which would
form the basis of a good Archive article.
8.2
(OK, Iæll see if we can get it out as an article next month. Ed.)
8.2
Sales Support
8.2
Where readers had hit problems before or after purchase and required
assistance, the standard of support varied widely. Cumana, Integrex,
Irlam and Technology Matrix all attracted pleasing comments, with
especial praise for both Morley and NCS (öexemplary ... service ...
customer supportò). HCCS had very mixed reviews, ranging from öexcellent
supportò (Archive 8.1 p40) to being severely criticised by two readers
(öHCCS basically didnæt want to knowò).
8.2
The bottom line
8.2
Anyone reading this survey from cold may form the view that SCSI systems
are difficult to master, fraught with problems and should be avoided.
This is not intended; there are lots of ticks on the table and every one
represents a successful, Éplug in and goæ situation. However, anyone
setting up a SCSI arrangement should anticipate that there may be
problems and, hopefully, this survey will help you avoid at least some
of them.
8.2
One recurrent theme in readersæ letters is that, where problems do
occur, you should not hesitate to ask for help. The best places to go
will be the SCSI interface manufacturers (generally) or, perhaps better
still, deal with a reputable supplier. Here are a selection of
unsolicited comments:
8.2
öVery few SCSI setup problems canæt be solved.ò
8.2
öAs one would expect, (NCS) eventually got everything sorted out OK Ö at
no time was I worried that I would be left with a scanner that would not
work.ò
8.2
öI would strongly recommend that anyone contemplating buying SCSI
equipment do so through a reputable Acorn dealer and describe clearly
what set up they are trying to achieve. If Iæd tried to do it myself, I
could easily have ended up with two devices that had the same SCSI
number, or had problems with setting up the connections.ò
8.2
Please do send me further reports which I will add to the database and
make available on request. And donæt hesitate to ask for more
information (usual rules: no SAE = no reply). Jim Nottingham, 16

Hints and Tips
8.2
Å  A3000 bulging case Ö My early A3000 had, from the start, a standard
Acorn monitor stand upon which was a AKF17 monitor. Of late, I found the
upper case section, on the left hand side by the power supply, had
started to bulge out from the bottom section. This was caused by the
weight of the monitor supported by the Acorn stand only on the extreme
edges of the case.
8.2
In my job as IT Technician at school, I had noticed (having removed
countless covers for various reasons) there have been two upgrades to
the cases, and one of the upgrades had special strengthening and
interlocking around this area, no doubt with this in mind. The latest,
Mk 3 version is available as an Acorn spare part. The base of the new
case requires a lot of work in removing the PCB and any upgrades, and
the power supply design has changed making the changeover awkward.
However the new case lid will fit onto the old base and this alone
offers enough strength to cure the problem.á K R Coton, Solihull.
8.2
Å  Disabling POST test (and other useful Ébitsæ) Ö One of our customers
found that because the POST (Power On Self Test, or the software that
makes the screen flash pretty colours at switch on and flashes the
floppy light at you when things go wrong), had been partly disabled,
meaning that his SCSI drive was not given sufficient time to get ready
before the SCSI card demanded its attention. Some people may have
disabled this after installing certain versions of the VIDC enhancer.
The POST will always be reactivated by a delete-power on, but there is a
more subtle way of switching it on or off. Byte 188 (&BC) of the CMOS
RAM contains 8 bits which affect various miscellaneous configuration
options.

The program disc contains a simple program for altering the state of any
of these bits.á David Webb, NCS.
8.2
Å  Inkjet printers and paper quality Ö A number of items have appeared
here and elsewhere on how to realise to the full the potential quality
of printouts with ink-jet printers. At 300 dpi, one would think it ought
to be indistinguishable from the output from a laser printer with the
same resolution.
8.2
Why is there a problem? All papers are made from fibres, matted
together; thus, if you put a drop of liquid onto a piece of paper, the
fluid will flow between these fibres, carrying with it any dye or
colourant: hence the fuzzy edges of the output from inkjet printers with
unsuitable papers. Coating the paper can eliminate the problem, but at a
substantial cost. However, with careful design of the paper making
process, it is possible to minimise (though not eliminate) this
Ébleedingæ.
8.2
I wrote to Hewlett Packard and asked for their recommendations They came
up with two types of paper and their suppliers. I got some samples, and
both were very good but, by a small margin, ÉVersoix Copyæ seemed to me
the better (and cheaper). The other, ÉReyjetæ, is close behind and both
are streets ahead of most ordinary photocopier paper. Neither is very
expensive (about ú3.00 per ream for Vesiox and ú5.50 for Reyjet) but
neither are very readily available. If you write to the distributors,
they will send you samples and the name of your nearest stockist.

8.2
Å  Irregular text frames in Publisher Ö In response to one of Keith
Parkeræs wish-it-did-that moans in the Comment Column (8.1 p31), I would
suggest that whilst irregular text frames would be nice, the use of a
regular frame öframedò by a couple of repelling irregular graphics
frames (drag an empty drawfile into blank frames) does the job, with a
little fiddling. áJohn McCartney.
8.2
Å  Large banners in Impression Ö To create a six foot long banner, or
similar, using Impression, create a new master page, öBannerò, width
72ö, depth 8ò, Landscape, margins 0.5 with one column. Quit the master
pages and alter the chapter of the document, selecting öBannerò as the
master page. Change the font size to around 400 point and centre the
text. Type the banner message. Print out on tractor fed continuous paper
(sideways!). Vector offers some useful banners ready made, or you can
use Impressionæs Borders in ÉAlter Frameæ, to enhance the finished
article.á Irene Quinn, Thetford, Norfolk.
8.2
Å  Laser Direct on the Risc PC Ö If you are upgrading to a Risc PC and
have an elderly Laser Direct card, it will not work if it is öIssue oneò
(the computer will not initialise after the board has been plugged into
one of the expansion slots). This type can be quickly identified by the
fact that it is the only version where there is a ribbon cable
connecting the circuit board to the printer output socket. Computer
Concepts will exchange this type of board for the latest version for
ú100. You will probably also need a copy of the most recent version
(2.63) of the printer driver disc at ú10.á David Smith, Edinburgh.
8.2
Å  More Sleuths on the case Ö If you are lucky enough to have lots of
memory on your machine you can run two or more copies of Sleuth at the
same time, so that if you are OCRing several pages of text, the rate of
OCRing can be considerably increased. On a simple test run, two copies
running saved 36% on the time taken and three copies saved nearly 50% on
the time! It then occurred to me that using more than one copy might be
infringing the software licence, but on checking with Risc Developments,
I was assured that this was not the case. áPhilip Foster, Cambridge.

Å  Turbo charging draft printing with a Deskjet printer Ö What I didnæt
realise, until I tried it by accident, was that the ÉDraftæ button on
the printer worked with graphic (e.g. output from Impression), as well
as Éstraightæ printing. Thus, with your printer driver set to 150ádpi,
and the Édraftæ light on, you can produce readable copies for proof
reading in virtually no time at all!á Barry Humpidge.
8.2
Å  Turbo Driver v4 and Dongles Ö If you are using CCæs Turbo Driver v4
on a computer with a bi-directional parallel port, via a dongle, the
status signals donæt get through. This includes signals, such as öpaper
outò and öprinter offlineò etc. If the driver software is looking for
these signals you may find that printing is blocked. To bypass the
problem call up the configuration dialogue box and configure to ignore
status signals.á Nick Harris, Norwich.ááAá

Tudor Monarchs & Tudor Clipart
8.2
Ed Archer
8.2
Tudor Monarchs is produced by Angelsoft Educational and contains a set
of three discs, thirteen worksheets and two manuals. The reason for the
three disc set is that Tudor Monarchs is basically an electronic book
which is run from the first disc containing a Magpie reader. This is a
sound idea in so far as it encourages both teachers and pupils to make
up their own electronic book. The way in which Magpie can be used is
well described in both manuals.
8.2
The first disc could have had more pages in it Ö this is a criticism I
would apply to all the discs, in that there was too much free space. I
thought the content was reasonable although there were several notable
historical inaccuracies e.g. Germany and Italy did not exist as
countries. Some of the pictures were poor, e.g. the view of the Star
Chamber was rather dark. On the plus side, the pop up pages were a very
good idea.
8.2
The second disc had some good sections such as the introduction to the
reign of Edward VI and I found the picture of the stake a moving touch
in relation to the religious persecutions in the reign of Mary Tudor.
The text could have been more informative, especially in the Drama
section. More use could have been made of Tudor music.
8.2
The worksheets were disappointing on two counts. First of all, there
were no illustrations and, in my opinion, these are vital to hold a
childæs interest. Also, the questions should have been framed in the
context of the 5-14 curriculum. This is of great importance to teachers
and needs to be addressed.
8.2
Tudor Clipart Ö Again, there seemed to be a great deal of wasted disc
space in the set of four discs. This amounted to more than one disc, and
I also felt that the clipart could have been compressed.
8.2
The manual was very useful and the tips regarding conversion from Draw
to Paint were very useful. It was very much to the point and was very
user friendly.
8.2
The actual contents of the discs was variable. In particular, on Disc 1,
I liked the portrait of Henry VIII but I did think that more care could
have been taken with the alignment of the pictures as several were off
the paper limits. I was especially impressed by the coat of arms and the
family tree on Disc 2 and the heads would be useful for the production
of worksheets.
8.2
Disc 3 of the clipart set was a mixed bag. The map of Wales was
excellent but more detail and explanation would have been very useful
for both the Flodden map and the Armada map. The ships on the disc were
of variable quality, although the one of the Golden Hind was very good.
8.2
Disc 4 also had its good and bad points. First of all, I did not know
they had rifles in Tudor Britain! The bibles were rather disappointing
and looked distinctly 20th century. The buildings and the country life
sections were the best ones on this disc.
8.2
My general view of the packages is that they represent a lot of hard
work but they do need some revision before I would give them an
unequivocal recommendation.
8.2
Tudor Monarchs costs ú20 +VAT and includes a site licence. Tudor clipart
costs ú15 +VAT but if you purchase both together, the cost will be ú30
+VAT from Angelsoft.ááA

PD on CD
8.2
Paul Hooper & Tony Stevens
8.2
(Ooops! I seem to have ended up with two reviews of the same product.
Iæll try to shuffle the two into one and, hopefully, end up with
something that reflects the views of both rather than the views of
neither! Ed.)
8.2
Paul Hooper starts...
8.2
As a frequent user of PD libraries, I have found that they are, like the
proverbial curateæs egg, good in parts. Certainly, there are many PD
programs on my hard disc that I would not be without and I have many
floppy discs filled with music, clipart, animations and other things
that may come in useful one day. The trouble is that, along with many
gems, there is an awful lot of PD that I would not give disc-room.
8.2
Now couple this with the huge storage capacity of a CD and it is a
classic recipe for a lot of ÉShovelwareæ. So how does this offering
measure up?
8.2
PDCD One from Datafile
8.2
The CD contains about 250Mb of data for a total cost of ú30. Now if you
work on the assumption that most PD discs cost ú1 a piece, the CD
contains about ú320 of software. Yet how much of this would you have
bought? Well, I thought I would go through my own collection of PD
material and see how much of it was now duplicated on the CD. I soon
worked out that, taking into account the clipart, I had well over 40Mb
of this material on a mixture of floppy and hard disc, so the thought of
freeing up all this storage space quite appealed to me. Also, that
amount of material has cost me well over ú50 when it was bought on
floppy disc.
8.2
Warning
8.2
I then set out to explore more of the disc and, with my six year old
daughter, I went through all the sillies and much of the clipart. When I
opened the box, I had noticed a small slip of paper saying that some of
the JPEG files were Éunsuitable for childrenæ and I steered well clear
of these until she was in bed. Iæm glad I did, because there were a
number of fantasy horror style pictures and also some images that belong
on the top shelf of a newsagents. Is it really necessary to include
files like this on a CD? The problem is that, being a read-only medium,
it is impossible to remove them.
8.2
The rest
8.2
Much of the rest is very good material although a number of the games
and utilities failed to work on my A5000 and how compatible these sort
of things are with the Risc PC is open to question. As David Holden said
in the PD Column last month, this looks like a CD that was put together
in a hurry Ö many of the utilities are quite old versions.
8.2
Tony gives a much more detailed breakdown of the contents, so over to
him...
8.2
(Tony was using a RiscáPC and had problems with quite a bit of the CD
not running properly. The Datafile are aware of these problems but the
CD was produced before they managed to get hold of a machine on which to
test the software. However, they are producing a module which will solve
90%+ of the problems. If you have already bought the CD and want a copy
of the module, drop the Datafile a line and they will send you a copy as
soon as it is ready. Ed.)
8.2
Getting started
8.2
Clicking on the CD icon opens a window containing an application called
!Database and fourteen directories; Animation; Clipart; Demos; Fractals;
Games; GamesDemos; Graphics; Languages; Magazines; Music; Raytracers;
Schools; Sillies and Utilities.
8.2
The Database application is a text reader for a comprehensive index of
the contents of the disc. Interactive help is available and should be
used to get the best from the application.
8.2
The Animations directory includes a copy of !Projector which shows files
from the Euclid package. The 26 animations all work and the quality is
high and the variety good.
8.2
The clipart directory contains a wide variety of items in both drawfile
and sprite format but as is usual with these large collections, there is
a wide variation in the quality. Some of it is frankly rubbish,
particularly among the collection of sprites, and I wish the PD
libraries would weed some of this out. There is also a lot of
duplication with several directories in the collection containing a
significant number of the same clips. A little more attention at the
editorial stage would have been sensible. Even so, this is an enormous
collection and the bad is more than adequately balanced by the good;
some very good indeed. Your own perception of the clips on offer is
going to be coloured by your particular needs, but the quantity ensures
that there must be something here for you.
8.2
There are 72 Demos in the collection but since the majority do not work
with the Risc PC I can make no useful comment.
8.2
The Fractals programs are all good examples of their type but at least
one locked up the machine when I attempted to exit to the desktop. You
wonæt be able to resist browsing and PD programs are notorious for poor
programming disciplines, so take a tip from me and temporarily disable
your auto-boot sequence, it makes the re-entry process less painful.
8.2
There are 72 games and 24 games demos, certainly enough to cause brain
death. Despite being warned that they do not work on the Risc PC, I
tried a few and some do work.
8.2
The graphics samples are supplied in GIF and JPEG formats. Donæt panic
if you do not have a loader, suitable programs are available from the
Utilities directory on the same disc. There are 306 separate graphics
samples on a wide variety of subjects and with a few exceptions, they
reproduce with an acceptable quality level.
8.2
For the programmer, there is a selection of eleven different program
languages, including Forth and a version of C.
8.2
Next comes a selection of four disc-based magazines. I could not check
these because some do not take kindly to the Risc PC.
8.2
The music collection consists of Coconizer with 22 tunes, SoundTracker
modules with 77 tunes and Symphony with 220 tunes. Coconizer would not
run on the wonder machine but SoundTracker and Symphony did. There are
plenty of tunes although the soundtracker songs are all very similar,
percussive and suitable for fourteen year olds writing yet another super
demo. The Symphony tracks, although born of the same family are
altogether more professional with good quality sound samples and a
smooth playing style which suggests some formal musical training
somewhere in the loop. Computer music fans will not be disappointed with
this section.
8.2
The next group of goodies are four Ray Tracing applications. I have not
tested any of these but I am sure they all work. At least one seems to
work on the Risc PC.
8.2
The Schools section consists of 36 programs, all useful, with plenty of
variety including chemistry; maths (including graphs); languages
(English, French and Chinese!); a typing tutor; telling the time; two
and four stroke engine simulations; educational games such as Scrabble;
and some quizzes. Some of the programs are suitable for primary
education.
8.2
The Sillies section has over seventy programs including classics such as
Loco Brolly and Deskduck. Some are amusing, some irritating and some
downright infuriating. Have you ever felt violent when the Silly wonæt
go away? Well donæt worry, if the desktop duck gets out of hand you even
have a program to shoot it.
8.2
For many people, the Utilities section will be the highlight of this CD.
There are over two hundred and eighty different utilities including a
spreadsheet, a number of databases including Superbase, text editors,
file and graphics handlers, font tools and comms utilities. It would be
pointless to try to list all of the features but, in addition to the
utilitarian, there are a number which provide information which is
either useful or of educational value. One such is the Gutenburg
Project, the purpose of which is to encourage the creation and
distribution of English language electronic texts. The sample included
on this disc contains no fewer than nineteen full length books including
the Bible, two of H.G.Wells books, the Alice books and the CIA World
Factbook.
8.2
Conclusion
8.2
Is it worth the ú30 asking price? I think that depends on your level of
experience and what you have already accumulated in the way of PD
software. There is a tremendous range of programs on this CD and even
though I have some top class dedicated programs, I have found a
significant number of interesting and useful items which I am looking
forward to exploring in some depth. You wonæt browse the contents of
this disc in one day.
8.2
Despite my own satisfaction, I cannot recommend this product
unreservedly to Risc PC owners, there are too many items which do not
work and, among those which do, a significant amount of duplication.
(But remember that this has been improved since Tony first looked at
this CD.)
8.2
If you do not use a Risc PC but already have a significant amount of PD,
you will need to examine the contents of the disc before committing
yourself. On balance, I feel you will not be disappointed.
8.2
The real benefit is to those of you who are relatively new to the Acorn
world or have a strictly limited budget. If that is the case, this CD
will provide competent programs in almost every important area of
computing activity.ááAá

According to TheoryáB, the chances are that you are being affected by a
disease of the heart called Éprideæ which affects a human beingæs
judgement. öAre you trying to tell me that for all the xxx years I have
lived on this earth I have been wrong in my view of God?ò Well, yes,
possibly.
8.2
Tell me, are you open enough in your thinking to investigate a new (old)
Theory? öNo thanks, I donæt want to end up a religious nutcase like you,
Paul.ò You see, you are at it again. Youære not approaching this coldly
and clinically and logically. Youære saying, öIæm not going to look into
this because I donæt like the implications. If I came to believe in
Theory B, Iæd be an object of ridicule in my family and at work.ò
8.2
Are you really prepared to examine the evidence for Theory B? Are you
really prepared to face up to the implications that follow if you do
come to the conclusion that the evidence is very strong that, for
example, Jesus did rise from the dead? Well, I tell you, all over the
UK, thousands of people are looking into it by going on these Alpha
courses, and thousands of people are saying that their lives have been
transformed by God in a wonderful way. I have seen my own 49-year-old
cousin change in a most wonderful way recently Ö he has such a peace and
a new joy Ö itæs just brilliant to see!
8.2
öHuh! Itæs getting worse! More religious mumbo-jumbo. Theyære obviously
being brain-washed! Silly people! I wouldnæt fall for that.ò Well, all I
can say is that, if it is brain-washing, it must be very clever brain-
washing because the people becoming Christians are taking their friends
on the next course Ö and they are going along because they can see that
something has happened to their friend and they want to know what it is.
8.2
öThis is getting ridiculous! The God-slot is getting longer and longer.
Religion is taking over the Archive magazine Ö and I paid good money for
it.ò Sorry about that but Iæll give you a pro-rata refund for the

ARM Programming Ö Part 5
8.2
James Riden
8.2
Sometimes, a particular project, such as a demo or game, will require a
large amount of graphics. The sprites may take up a lot of space on disc
and the time taken to load them can become irritating. This month, we
are going to look at a solution to this problem in the shape of data
compression.
8.2
The easiest algorithm is known as Érun length encodingæ. It makes use of
the fact that a lot of data in sprite files is repeated again and again.
For example, if you saved your desktop screen with Paint, there would
probably be many uninterrupted rows of grey background. Assume for the
moment that we are using a 256 colour mode. Stored in a sprite file, a
row of 100 grey pixels would take up 100 bytes. However, if this were
stored as a value representing the grey colour and another value to
indicate the number of pixels in the sequence, this could then be stored
in two bytes.
8.2
Sadly, in real life things are not quite that simple. If we tried to
compress a screen using this method, and no two adjacent pixels were the
same, we would need two bytes to store each pixel Ö one for the colour
and one more to tell us that there is only one pixel in this sequence.
So we would make the file double its original size.
8.2
A good solution is to store sequences as either Édifferentæ sequences or
Ésameæ sequences. If three or more bytes are the same, we can gain by
encoding the sequence (because it will take only two bytes to store).
Therefore we store the following:
8.2
same flag [1 bit]
8.2
number of same bytes [7 bits]
8.2
value of bytes [8 bits]
8.2
This still only takes up two bytes but we can only use it for sequences
for up to 127 repeated bytes since we need one bit as a flag. Now if we
have a Édifferentæ sequence, we can store the number of different bytes
following and not waste space on the frequency of each individual byte.
For example, to store the sequence 124,56,78,55,1,45 we scan through
until we have got to the end of the Édifferentæ sequence and then output
:
8.2
different flag [1 bit]
8.2
number of different bytes [7 bits]
8.2
first byte, second byte, third byte, etc.
8.2
 [8 bits each]
8.2
So, in this case, we would store 6,124,56,78,55,1,45.
8.2
We are therefore able to store dissimilar sequences fairly efficiently.
Now we need to write down a örecipeò for our routine and then implement
it. Note that, in practice, a Édifferentæ sequence is terminated when we
find a Ésameæ sequence. I am assuming that the flag is kept in the byte
used for frequency.
8.2
load two bytes
8.2
if they are different then
8.2
  carry on loading bytes until we find three
8.2
 or more similar in a row or we
8.2
 finish the input data
8.2
  store the Édifferentæ flag
8.2
  store the number of different bytes
8.2
  store the sequence we have just scanned
8.2
endif
8.2
if they are the same then
8.2
  carry on loading bytes until we find a
8.2
 dissimilar byte
8.2
  store the Ésameæ flag
8.2
  store the number of same bytes
8.2
  store the value of the same bytes
8.2
endif
8.2
To restore the compressed file is much easier. We need to go through the
data and either load once and store many times or load and store many
times.
8.2
load a byte
8.2
if the Édifferentæ flag is set then
8.2
  initialise counter with the number of
8.2
 different bytes
8.2
  load a byte and store it
8.2
  decrement counter and loop if necessary
8.2
endif
8.2
if the Ésameæ flag is set then
8.2
  load byte containing value of same bytes
8.2
  initialise counter with the frequency of
8.2
 same bytes
8.2
  store the value of the same bytes
8.2
  decrement counter and loop
8.2
To implement this, we need to decide what is to be done about sequences
of more than 127 bytes. Either we can terminate the sequence at 127 or
we can scan how many there are and then break the total down in 127 byte
blocks. To a store sequence of 300 bytes of value 34 we can store
[127,34,127, 34,46,34] which is still a very effective compression
ratio.
8.2
At each load, you need to check that you havenæt run out of data. If you
are compressing a mode 12 or a mode 13 screen then remember that they
are 81920 bytes long and you need to stop and output the current
sequence when you get to the end.
8.2
Try it and see how you get on. A copy of my program is on the monthly
disc in case you need to look at it. If you have any suggestions for
future articles, perhaps you would leave a message with Paul at the
Archive office.ááAá

Squirrel 2 Update
8.2
Tim Nicholson
8.2
In Archive 7.5 p67, I reviewed version 2.00 of Squirrel, and concluded
that, although the program had promise, it contained a number of bugs,
some quite serious, which severely limited the benefit of upgrading from
version 1.xx. I promised to report on the progress of version 2 as
Digital Services sought to iron out the problems. I had hoped to be able
to do so sooner but unfortunately development took longer than expected.
8.2
Now and then
8.2
At the end of 1993, an intermediate version 2.03 was released which was
claimed to fix the reported problems. However, apart from fixing the
serious problem which prevented use of the compression option, and one
or two minor tweaks, the problems reported in the earlier review were
still present. Some had altered slightly in their effect, but they still
prevented correct operation of some facilities. I sent Digital Services
a list of the problems that I had found still to be present, together
with sample files which demonstrated the faults. I requested them to
suggest solutions or workarounds until the problems had been fixed.
Although the reply I received did not answer my specific points, it
sounded hopeful, and I quote, öI have reported the problems you have
encountered and you should find these fixed shortly... ...May I suggest
you contact us in four weeks or so to request a new version.ò
Unfortunately, this time scale proved to be wishful thinking and
eventually, after several phone calls, I received a copy of 2.07 in
June.
8.2
As I worked my way through the new version, I discovered that although
many problems had been attended to, a number of areas where I had
reported difficulties appeared unchanged. I again wrote to Digital
Services pointing this out, and again requested help on the particular
items which were outstanding. Their reply this time was less
encouraging, and I quote, öWe will investigate the problems reported and
the result of this should appear in the next release. We do not have a
date for this release currently, but I can inform you that it is not
imminent.ò Once again no comment was made on the items for which I had
specifically requested help. I therefore proceeded to prepare my update
article on the basis of version 2.07 and the information, or lack of it,
I received from Digital Services. As I did so I came across another
öfeatureò of Squirrel which I had not previously been aware of, and
which caused me to become even more disenchanted with the support I had
received. This was reflected in that article, which Digital Services
felt was unrepresentative. However, it did serve to make them respond to
the particular issues I had raised, and produce version 2.08 rather more
quickly than they might otherwise have done! The following comments then
are based upon my look at 2.07 amended where necessary by changes in
2.08 and the responses I eventually received from Digital Services.
8.2
The acid test
8.2
A number of interrelated problems were to do with the new List mode
feature and, frankly, as it had stood, it was unusable. I was delighted
to find that all the problems I had encountered had gone. Sorting worked
on the selected field, switching between Card mode and List mode could
be done with impunity, and although GOTO was still not on the List mode
menu, it could be engaged with the <f5> Éhot-keyæ shortcut. The toolbar
buttons also correctly mimicked the Page Up/Page Down buttons. In short,
this section now worked properly and could be used fully, I was
delighted.
8.2
I moved on to look at default entry. This had not worked correctly for
date fields and could cause error messages, the problem is now resolved
in 2.08.
8.2
I turned my attention to Batch updating. I had had problems with date
fields when trying to batch update an age field. Once again, there was
still a problem, albeit minor. A batch updated age field which was
specified as a numeric type insisted on displaying an age in the form
AA/00/00, although this only occurred when in the Batch Query view. When
looked at normally, the display was thankfully correct Ö according to
Digital Services, this problem will occur if the type of a field is
altered whilst a Query window using that field is also open. The Query
reflects the old field type and not the new one. This situation is
easily avoided, and I had got into it because I had expected the AGE
function to return a full days/months/years result. However, since
calculated fields are always numeric, the returned result is only the
years part of the answer. This rather limits the usefulness of the
function. Other calculations involving dates produce results as a number
of days which is accurate if not easily interpreted without further
massaging.
8.2
Next I looked at the Graphing mode where I had encountered a problem
with the count function. This is designed to produce plots of sizes of
groups by counting the number of records where a field matches a
particular parameter e.g. age. I had a simple pie chart to plot the
number of people in each age range against that age. Instead of getting
one group of size X for those of age N, I sometimes ended up with X
entries of people aged N each with a size of one. According to Digital
Services, this behaviour is because the sort order affects the grouping
in the graph, but I could find no mention of this in the manual, which
is at great pains to point out this feature in relation to nesting
within reports. I hope it might find a mention in the errata file which
is supplied with upgrades, and which has been added to significantly in
this latest release. Indeed it now includes a warning about the
potential problems of merging mismatched tables which I had encountered,
and numerous hints and tips making it an important read when upgrading.
8.2
One problem which I have not reported on before, came to light when I
set about upgrading my hardware from an ageing A440 to a Risc PC. As an
interim measure, I have taken to using the childrenæs A3010 with an
Atomwide Printer/SCSI adaptor and my original external hard drive
containing my main applications, including Squirrel. At this point, I
discovered that Squirrel version two will only run on the machine on
which it is installed/upgraded. When run, it checks the unique machine
ID which is provided in the later Acorn machines. If the number doesnæt
tally with the number it found when installed/upgraded, it reports the
fact and steadfastly refuses to run.
8.2
Using the unique machine ID in this way is against Acorns guidelines,
but Digital Services say that they find it necessary given the poor
level of copyright law awareness, particularly in schools, where
Squirrel is an ideal application, and is easily used/misused on
networks. Whilst this is a valid point, it is imperative that some
method of re-installing the application on another machine is available
for genuine users. At the time I discovered this problem (some 9 months
after the release of the product) Digital Services did not have any such
system. It took them a week to get me a beta test of a utility (which
partly solved the problem) and another week to get me a proper working
version. In the meantime, I was unable to access my data. This utility
is now available to individual registered users on an öas-neededò basis.
8.2
Looking ahead
8.2
All of the problems reported with the earlier versions of Squirrel have
now either been dealt with, or the correct usage explained in an
extended errata file. Digital Services say they are continuing to
develop the product and I hope that string manipulation is high on their
list. With BTæs Phone Day rapidly approaching, I am not looking forward
to updating all the phone numbers in one of my databases by hand. The
ability to use substrings (as in Basicæs MID$ function) in batch updates
is becoming pressing! The ability to parse and merge strings in reports
would also be most welcome.
8.2
Conclusion
8.2
In version 2.08, Squirrel performs as it should. My only disappointment
is the time it has been in coming, and the responses I have received to
my difficulties on the way. Its inherent power and flexibility can
sometimes work against it, making it easy to use rather than easy to
learn, especially if the manual is misleading on the operation of some
function or other. Its new facilities significantly improve its
performance over version 1 and the product appears to be stable and well
behaved. However I remain far from happy with the support I have
received from Digital Services.
8.2
It may be that I have been unlucky, and am not a typical case, but the
manner in which bugged versions have been released, and software
protection policies not thought through fully, leaves me with distinct
disquiet over their general thoroughness, be it beta testing or customer
support. It would be a shame for a good product to suffer because of it.
For myself, I will have to think very carefully before buying another
product from the same company. However, for those thinking of investing
in Squirrel, the product is at a stage where the need for customer
support should be at a minimum.
8.2
Squirrel 2 costs ú139 +VAT or ú150 through Archive. Existing users can
upgrade to version 2 for ú25 +VAT or ú35 +VAT including a revised
manual. Upgrades are only available from Digital Services.ááAá
8.2
Weæve been in contact with Steve Taylor of Digitial Services throughout
the discussions over the Squirrel updates and Timæs comment about them.
The following comments from Steve arrived too close to publication to
give Tim the opportunity to read them. Ed.
8.2
Steve Taylor of Digital Services replies...
8.2
The article runs through a potted history of minor problems and bugs
which Mr Nicholson believes he has encountered, and this results in the
overall tone of the article being the most negative we have ever
encountered. This is despite the fact that he is actually complimentary
about the product. Indeed, he states that version 2.08 performs as it
should in appearing stable and well-behaved. He also mentions its
inherent power and flexibility.
8.2
I must emphasise that Digital Services are an extremely conscientious
company that truly cares about its products and the satisfaction of our
user base. I can provide lists of satisfied users both in education and
business, and unsolicited complimentary letters praising both our
product and our level of support. We have sold several thousand copies
of Squirrel but have never received feedback as that from Mr Nicholson.
8.2
I would state that, whilst Mr Nicholson has reported valid bugs to us in
the past, these have all been fixed, and a significant amount of his
previous feedback has been caused by user error and a lack of
understanding of the product.
8.2
Regarding the statements on our software protection system, we do
understand Mr Nicholsonæs concerns and would make the following
comments:
8.2
It is each publisheræs right to define his own licence conditions, and
like a significant number of PC programs, our licence dictates that
Squirrel can only be used on one computer. The software licence policing
is totally transparent until the end user has BROKEN the agreement, and
therefore does not inconvenience those using the program legally. I
would also state that Acorn have examined our terms, and do not object
to our methods. We do recognise that, under a minority of circumstances,
whereby a user has a removable hard disc or is upgrading his machine,
the system is extremely inconvenient, but a simple telephone call to
Digital Services will result in an immediate resolution.
8.2
Finally, I cannot stress enough that Digital Services feel this article
is unrepresentative of both our product, and our company, and assure
readers of our dedication to quality.
8.2
Two final comments from me as editor. Firstly, in a letter I received
from Acorn, they stated that öAcorn does not support the direct use of
the machine ID as a protection device. Acornæs Software Protection
Scheme uses the ID but specifically does not prevent an application from
running; it only provides a warning to the userò and they said that they
would öremind Digital Services of thisò.
8.2
And secondly, I have tried to be fair to both parties in this
disagreement. If what has been printed has offended either of them,
please accept that, as a magazine, we try to tread the middle line,
giving contributors the opportunity to say if they think a supplier is
not giving good service and, where possible, giving suppliers the right
of reply. This is what I have tried to do as fairly as possible. Who
would be an editor!ááAá

Image Master
8.2
Robert Chrismas
8.2
Image Master deals with bit image graphics. It can acquire, process,
print and save images. Other programs on the Image Master disc convert
bit images to drawfiles, capture images from the screen, convert
drawfiles to outline fonts and use a scanner and a Laser Direct printer
to act like a photocopier. Even if you do not need all these facilities,
Image Master may still be good value because its price is very
competitive. (ú28 through Archive.)
8.2
File formats
8.2
When my college bought Image Master, all we wanted was a program which
would convert bit image graphics into different formats. In particular,
we wanted to be able to transfer bit image graphics between Archimedes
computers and IBMs without fuss. Image Master can load and save graphics
files in these formats: Clear, GIF, PCX, MTV, BMP, PBM, JPEG, TIFF and
sprite.
8.2
Some of these formats have different Éflavoursæ. Just as there are one,
two, four and eight bit sprites, TIFF files can be monochrome or colour
with different compression techniques; BMP files can be OS2 format; JPEG
files have different quality settings and so on. Image Master has been
adequate for all our file conversion tasks. However, I have not tested
all the possible formats. Does anyone know of a program that can read
MTV files?
8.2
I have had a couple of problems with file conversions. The first was my
fault. I had a directory of PCX files which included a ReadMe text file.
Without sufficient care, I set all the files to PCX type, including the
ReadMe, and proceeded to load each one into Image Master. The ReadMe
file caused Image Master to crash. This was my own fault but a öcanæt
make any sense of this fileò message would have been a better response
than an unexpected exit.
8.2
More seriously, when I attempted to save a file to a filing system which
did not have enough free space, Image Master froze the whole desktop.
8.2
There should be terms for programs which quit without being asked to
(crash and burn?) and which lock up the whole machine (seize a wimp
poll?).
8.2
These problems have not made Image Master unuseable but I do make sure I
save important files before running it. David Pilling has a good record
for upgrading software so if you find a popular format which Image
Master cannot handle, a phone call will probably produce a version which
can. (This is not promised Ö it is just my belief based on experience
with David Pillingæs software.)
8.2
Because of my success with file conversions, I recklessly offered to do
this review, only to find myself wrestling with Gamma Correction and
convolution filters. We learn by our mistakes.
8.2
Big files
8.2
Image Master can handle 24 bit per pixel images. It will also load and
save the new Acorn 16 and 32 bit sprite formats. These formats can
result in very big files. Image Master can handle images which are too
large for the computeræs memory, processing the image in sections.
8.2
In screen modes which cannot display all the colours, Image Master uses
dithering to represent the colours as accurately as possible.
8.2
Scanning
8.2
Twain is the name of a general scanner interface. With Twain, any
program can use any scanner, just as, with RISC OS printer drivers, any
program can use any printer. To make this work, you need a Twain scanner
driver set up for your scanner. Then other programs, like Image Master,
can send standard Twain commands to the scanner driver which will send
back images.
8.2
Image Masteræs Twain compatibility only means that it can talk to a
Twain driver. Happily, Twain drivers for a range of scanners are
available from David Pilling at very competitive prices.
8.2
I have not used Image Master for scanning. However, in ÉColour Scanning
Revisitedæ (Archive 7.10 p44) Jim Nottingham discussed the suitability
of Image Master coupled with a Twain driver for colour scanning. Jim
included some comments he had received from Richard Readings. Richard
had version 1.01 of Image Master. Some of his criticisms have been
answered by the latest version. In particular, version 1.03 now has an
undo option. In fact, the user can specify the number of steps to be
held in the undo buffer.
8.2
Both Richard and Jim seemed to feel that the Image Master/Twain link was
good value for scanning software but Jim warned that attempting to use
it with a scanner bought from a ödeep-discount box-shifterò might lead
to compatibility problems which neither the scanner supplier, the SCSI
interface manufacturer nor David Pilling would want to know about.
8.2
tool box  & info palette
8.2
Processing
8.2
The current image is displayed in the main window. There are also a
toolbox and an info palette window.
8.2
One tool allows you to select a part of the image. You might do this to
crop the image, but it is also useful because, if an area is selected,
the filter and colour processing options will only apply to that area.
There is a zoom control and the image can be moved around the window.
8.2
On the main menu, the Éfileæ option leads to saving, printing and
scanning.
8.2
The ÉViewæ option allows multiple views of the same image. With files
which contain more than one image, this option will allow you to step
through the images. Other options on the ÉViewæ menu control which
windows are displayed, the units of measurement and the print border.
8.2
ÉEditæ includes the expected items for cropping, rotating, mirroring,
shearing and scaling the image.
8.2
The Edit options are an example of both the good and the bad aspects of
Image Master. In some programs, like !Paint, the scale option reduces
the size of the image by deleting some of the rows and some of the
columns. So, for a 50% reduction, !Paint would delete every other row
and every other column. However these rows might have contained
important details. Image Master calculates the colour of each pixel in
the final image taking into account all the pixels in the original image
which would affect it.
8.2
This is the same sort of calculation that the font manager does to
represent very small characters on the screen using pixels which can be
a range of greys instead of just black and white. This sort of
calculation is called anti-aliasing.
8.2
80% reduction with anti-aliasing
8.2
Now Image Master is very good at anti-aliasing. All the Edit options can
have anti-aliasing. Image Master allows the user to select one of seven
different anti-aliasing algorithms: Hermite, Box, Triangle, Bell, B-
spline, Lanczos and Mitchell. It also has an option for no anti-
aliasing.
8.2
The first bad thing about this anti-aliasing is that the menu to choose
the anti-aliasing system is on the configuration window which in on the
iconbar menu. There is no obvious connection between this and the Edit
option on the main menu.
8.2
The second bad thing is that the manual does not explain the differences
between these algorithms. Now I suppose that is fair enough. To explain
all that Image Master does would take a text book on image processing
not a program manual. However, you should bear in mind that if you are
not already an expert on image processing, you will need to experiment
with some features to discover just what they do. And in the case of
anti-aliasing, you may still be in some doubt.
8.2
The third bad thing only became apparent when I tried to produce a
diagram to illustrate anti-aliasing. There is an option to select no
anti-aliasing, but when it was selected, scaling was still anti-aliased.
8.2
Filter
8.2
A Éfilteræ is a process which calculates a new value for each pixel
based on the original value of that pixel and the other pixels near to
it. Filters are often used for removing noise or sharpening images.
There was a very helpful explanation of image filtering in a series of
articles by David Knell in Acorn User back in 1990, June Ö November. The
June and July issues would be the most useful for confused users of
Image Master.
8.2
A convolution filter replaces each pixel with a weighted average of the
surrounding pixels. The Éuser filteræ option allows the user to specify
the weight of each pixel. Some of the more common filters are provided
with Image Master so they can be easily loaded.
8.2
Maximum, minimum and mean filters are also available and there is an
option which will add noise to the image. Adding noise sounds strange
but if you have an image which has been scanned with only a few
brightness levels, a small amount of noise can make the image look less
Éflatæ. There is also an inverting filter.
8.2
The filter menu also includes the ÉHistogramæ option. This Éfilteræ can
be applied to red, green or blue components of the image or to any
combination of these components. When the option is selected, Image
Master counts the number of pixels at each brightness level and displays
the result as a histogram.
8.2
öThe Éequaliseæ button attempts to spread out the pixels in the image so
that there are equal intensities in each bandò Ö or at least that is
what the manual says. Now I would have thought that Éequaliseæ might try
to get an equal number of pixels in each band. Equalise certainly
changes the colours in the image, but I am not quite sure what it is
doing Ö the columns in the histogram do not end up the same height or
anything obvious like that.
8.2
There is also an Éexpandæ option which spreads a selected range of
intensities to occupy the whole range. This changed the colours in the
image in a way which I found much more predictable. When you select
equalise and expand, the image changes but the histogram does not. To
update the histogram, you have to click on recalculate. I think it would
be better if the histogram were recalculated automatically although I
can see that might be difficult to implement.
8.2
(In retrospect, I think my difficulties with the histogram option may be
due to my inexperience rather than any inherent problems with the
application.)
8.2
Colour
8.2
The final option on the main menu is Écolouræ. Filters change the colour
of a pixel using information about surrounding pixels (in the case of
the histogram option, all the surrounding pixels). The colour option
includes all the processes which change each pixel using an algorithm
which does not require any information about surrounding pixels.
8.2
ÉSwopæ simply interchanges the red, green and blue components. So, for
example it can swop red and the blue.
8.2
ÉGrey scaleæ converts a colour image to shades of grey. The weights of
the red, blue and green components can be adjusted but the defaults are
fine for normal purposes.
8.2
The Écolour balanceæ option uses the HSV (hue, saturation, value) colour
model. Using sliders, you can change the overall contrast, brightness
and saturation of the image. The hue slider allows you to rotate the hue
of all the colours by a percentage of one complete rotation. The manual
says this sort of adjustment might be useful for correcting discoloured
scans.
8.2
The most precise control over colour intensity is achieved with the
Énon-linear controlæ. Like the histogram filter, this can be applied to
red, green or blue components of the image or to any combination of
these components. A graph controls the mapping from input brightness to
output brightness. I found this control intuitive and easy to use. The
mapping can be continuous or in discrete steps which will give the image
a flat Époster colouræ appearance.
8.2
The Énon-linearæ graph should help to make clear the meaning of the
gamma correction number ÉGæ. To take an example, if G=2 then, after
processing, the brightness of a pixel will be the original brightness
squared, the non-linear graph will just be an x▓ graph. (Maximum image
brightness is scaled to 1.) In general,
8.2
output brightness = (input brightness)G
8.2
Tint, filter, add and subtract
8.2
The Étintæ, Éfilteræ, Éaddæ and Ésubtractæ options on the colour menu
allow you to make global changes to the colours of the image. One
process Éaddsæ a chosen colour to every pixel of the image, another has
the same effect as viewing the image through a coloured filter. ÉTintæ
and Éfilteræ are words which crop up with different meanings at
different points in Image Master. There is a Éfilteræ option on the main
menu and another on the colour menu Ö I found this confusing at first.
8.2
With the palette option, you can inspect and edit the palette of the
current image. The right hand part of the palette window allows you to
choose colours using the RGB, HSV or CMYK (cyan, magenta, yellow, black)
models. Chosen colours can be used to change entries in the palette.
8.2
The palette also allows you to specify the Éforegroundæ colour which is
used by the tint, filter, add and subtract options. The control which
determines how much effect the foreground colour will have is labelled
ÉTintæ. This terminology is confusing but the option certainly produces
some very interesting effects.
8.2
Change format
8.2
Change format is a very powerful option but I am not sure that it
belongs on the ÉColouræ menu. Change format allows you to change the
image from one sprite format to another. You can change the number of
bits per pixel, and the type of palette. Current formats are 1, 2, 4, 8,
16, 24 and 32 bits per pixel. Palette options include the standard RISC
OS desktop palette, a calculated Éoptimalæ palette, digital RGB and a
linear grey scale.
8.2
If you decrease the number of bits per pixel, there will be fewer
colours available in the palette. It may not be possible to represent
all the original colours accurately. The least sophisticated strategy is
just to choose the colour in the new palette nearest to the original
colour. Change format can do this but it can also be set to match
colours with patterns of different coloured pixels which ours eyes
Éaverage outæ as the original colour. So, for example, alternate white
and red pixels, if they are small enough, will appear to us as
continuous pink.
8.2
We are familiar with this process in printing where patterns of black
ink and white paper are used to represent different shades of grey. In
traditional half-toning, the patterns are regular repeating designs. A
longer calculation called ÉFloyd Steinberg ditheringæ gives the pixels a
more random appearance. Dithering will display details which might be
lost in half-toning.
8.2
As you would expect, Image Master has options for what it calls
Éorderedæ dithering (half-toning) and Floyd Steinberg dithering of
several different types.
8.2
Other programs
8.2
Image Master comes with a number of other programs. ÉTraceæ creates a
drawfile from a sprite file by tracing the outline of each colour.
ÉSnapperæ captures the whole screen, a window or a menu as a sprite.
ÉD2Fontæ converts a drawfile to an outline font. ÉZeroæ combines a Twain
scanner and a Laser Direct printer to work as a photocopier.
8.2
Each of these programs is worth at least a short review of its own.
(Trace was reviewed in 5.4 p61 and 5.6 p25. Any offers to review the
others? Ed.)
8.2
Documentation
8.2
The manual covers all the features of the program and goes some way to
explaining the theory behind them. However, this is obviously a big
subject and it is not reasonable to expect the documentation to cover it
all. One particularly useful section on file formats gives some
background information on each of the file formats which Image Master
recognises.
8.2
Comments
8.2
Image Master is a fairly big, powerful program. It combines scanning and
image processing with the ability to save and load bit images in
different formats. I know that some users like programs with lots of
features. However, I think there is a case for more small programs. The
RISC OS desktop makes it so easy to pass data between different
applications with in-memory file transfer, that we do not need to have
programs which do everything themselves. I like Image Master, but I
think I would like it better if it came as three separate programs.
8.2
The Trace program is capable of Ébatch processingæ. You drag a batch of
bit images onto its icon and Trace creates a directory with drawfiles of
the images. It would be useful if Image Master could perform file
conversions in the same way. The user would specify the format in which
the images should be saved and then Image Master would convert a whole
directory full of images in one go.
8.2
Image processing is a skill. It takes skill to decide how to combine the
processing features of Image Master to produce the effect you require. I
have seen someone who was quite incapable of producing an acceptable
scan of an old photograph gasp with astonishment when a few adjustments
produced a clear image. To get good results from Image Master, you need
to understand how computer images are stored and you have to be able to
look closely at the image and to think. There is a lot to learn here,
and I for one would welcome some articles in Archive by experts on image
processing.
8.2
For a user like myself who has only limited experience of image
processing, some of the menu entries and the layout of some of the
windows were confusing. However, it was possible to work out what was
going on with the aid of the manual, and I do not find it easy to
suggest a more intuitive design for such a complicated subject.
8.2
Conclusion
8.2
Image Master combines scanning and image processing with the ability to
save and load bit images in different formats.
8.2
Release 1.03 which I reviewed is a little fragile. It has crashed a few
times on my A5000 and some options have given surprising results.
8.2
The program has an impressive range of powerful features and for ú30
(ú28 from Archive) it is excellent value. At this price, it is worth
buying even if you do not need all the features.ááAá

Penfriend
8.2
Christopher Jarman
8.2
The test of any good invention is whether it does exactly what it sets
out to do. The test of an outstanding new invention is whether it does
even more things than the designer thought possible. Penfriend
definitely comes under the second category!
8.2
It has been reviewed already in Archimedes World and has even been
issued as a demo on their March 1994 disc. While it has had good reviews
from people seeing it as an aid to children who may be disabled in
various ways, I believe it offers far more opportunities for creative
writing than this.
8.2
Original designs
8.2
The designer, Roger Spooner, well-known for his original ideas in
programs such as Calligrapher, has seen the need for a predictive typer
which will finish off words for hesitant or physically handicapped
writers. The default lexicon (wordlist) contains about 1100 words but it
will accept a vocabulary of up to 15,000 words if required.
8.2
Penfriend loads easily onto the iconbar from floppy but, like many
applications, it works more quickly and easily from a hard disc. The
manual, which is a clearly-written 33 pages, is a model of how to write
for beginners. It explains in simple English all you need to know even
if it is your first day on the Archimedes. If only other manual writers
would follow this pattern!
8.2
When a letter key is pressed, Penfriend immediately displays a list of
up to eight of the most likely words you might be looking for, from the
current lexicon which you have loaded. The words are in order of most
frequent use, and each one can be summoned by a function key. So, you
might type Éwæ and the list of words; was, with, will, which, what,
when, wonderful and so on will pop up. Merely by pressing <F7>, the word
Éwonderfulæ will then be typed. I have just used Penfriend myself to
write that last sentence. It sounds complicated when described but, like
many typing helps, it is much easier in practice, and practice makes
perfect! For someone who finds typing a physical challenge or is very
unsure about spelling, Penfriend acts just like a supportive friend. It
is a Spellcheck in advance rather than the usual öBleep!ò which means,
öWrong! You stupid boy!ò.
8.2
More options
8.2
If this was all that happened, the program would still be well worth
buying, but there are more options. There is a keyboard window whereby
the mouse may be moved around a simulated keyboard on the screen. I know
there are PD versions, but this is very good. It works well with all the
other applications I tried such as Edit, Phases and even Optima; if I
only had the use of one hand and one finger, I could easily have written
a complete multimedia package using the mouse and the Penfriend
keyboard!
8.2
The sticky keys option is very handy for someone who has to type with
either one hand or two fingers. Control or Shift can be held down for a
moment to make a capital or whatever else you need. Different bleeps
remind you of your actions. There are other typing options such as
öClever Punctuationò and öIn-line Predictionò which are explained in the
manual. The program will also add every new word that you type to the
current lexicon if you wish, thereby teaching it your own vocabulary as
you go.
8.2
Editing the lexicons
8.2
What makes this product so exciting is the extra program called Editlex
which comes with it. It is designed to modify the lexicons in use, and
to put together new ones. The original idea was that different children,
or other users, would have their own particular style of writing, and
commonly used words which they would build up. Indeed, this is a very
useful way of personalising the program. However, by extension of this
idea, it is possible to create lexicons using very particular language
or even foreign languages. By merely dragging a plain textfile into a
lexicon window, you may set up a new wordlist. Imagine scanning a chunk
of Chaucer and putting the subsequent textfile into Editlex and starting
to type! All your predicted words would be from Chauceræs vocabulary.
You could soon be writing very genuine looking pastiches! I have a
dictionary of Royal Navy slang called öJackspeakò which has recently
been compiled and, by typing a sizable chunk of it into Edit and
dragging it into a Lexicon, I can now write to my old friends in RN
argot without having to rack my memory for the correct terms. Think of
the fun in English lessons! Write an essay in Tolkeinæs elvish, for
example, or write like Damon Runyon. Copy a few Shakespeare sonnets into
Editlex and then choose your words carefully. I also have a dictionary
of Australian slang Ö I think perhaps Iæll load it up and try writing an
episode of Neighbours Ö the trouble is that the program will insist on
describing itself as öPenmateò! (or öPencobberò? Ed.)
8.2
Penfriend is available from Design Concept, price ú25 plus ú2 p&p. Site
licences are free for up to five machines.ááAá

Eagle M2 Multimedia Card
8.2
Paul Hooper
8.2
One danger in writing reviews is the temptation of rushing in an effort
to get it into print before all the other magazines. This can lead to a
superficial review in which much of the material is just a regurgitation
of the manufactureræs handouts or press releases. Iátry, as far as
possible, to resist the scoop approach and subject the hardware or
software to a sustained period of use before committing the review to
paper. The trouble is that, sometimes, a piece of hardware comes along
that has so many features and so much associated software that the
review process can take weeks. Such is the Eagle card.
8.2
The card
8.2
The packaging is a dull cardboard box but the contents are far from
dull. You get a standard size expansion board with a flying lead, no
less than three manuals and loads of discs. The card was tested on both
an A5000 and a Risc PC. Although the manual had no fitting instruction
for the Risc PC, it is fairly obvious where the flying lead goes. A Risc
PC errata sheet should be out by the time you read this.
8.2
The back of the card has four connections:
8.2
a)áSuper video connector (4-pin mini din) for S-VHS, Hi8 or Hiband
sources.
8.2
b)áBNC (bayonet-style) connector for CVBS, video out (VHS) or SCART
sources.
8.2
c)áMidi connector (15-pin D-type socket) for use with Midi sources.
8.2
d)áStereo audio (5-pin din) live-level connector for use with CD
players, amplifiers or Hifi equipment. This has both input and output
connections so that sound can be received from or sent to your computer.
8.2
There is only one lead supplied and this is for the Midi connector. The
rest of the leads you will need to supply yourself.
8.2
Video connections
8.2
Supplied on disc is the latest version of the Acorn Replay utility and
this needs to be decompressed with CFS onto your hard disc. Also
supplied is !TakeTwo which enables you to capture colour sprites, TIFF
or Clear files from a video source or Replay movie. If you want to
capture greyscale sprites then the Scanlight software is also supplied.
8.2
Connection to a video source can be a nightmare: for my video camera, I
have a video out socket which is a normal phono socket, but my VCR has a
SCART socket. Two leads were obtained from my local Tandy shop and I
first connected the video camera. I could record video from the camera
but no sound. The same problem was experienced with the VCR Ö I had
bought the wrong leads! Twenty pounds poorer and with advice from
Matthew at NCS, I managed to get the right leads and got connected to my
video camera.
8.2
Up and running
8.2
Once TakeTwo is installed, you can get a Élive displayæ by clicking on
its icon. The live display is just that Ö even on my old 24MHz A5000,
the display kept up with all the movement recorded via the video camera.
There must be some very clever electronics on this board to achieve
that!
8.2
<Menu> over the display allows you to control the picture. The video
source can be specified as composite or S-video, PAL or NTSC and these
can be live or tape. You can also control the display with Auto-Zoom
with a 4:3 lock or free aspect ratio on the picture. The alternative to
Auto-Zoom is Pan and Scan.
8.2
Before you can save anything you have to set up your Grab Choices from
the menu. The grab menu is as shown below and the file icon must be
dragged to a directory before you can save your file.
8.2
Working from the top, you must first specify the file type. You have a
choice of Sprite TIFF, Clear and Replay. To make this easier to
understand, I have set out the options for each of the static files in
the table below. The choices for Replay files are shown in the pictures
of the menu system but it all depends what computer you have as to how
many of these you can choose. Certainly, my old 24MHz A5000 could not
take in colour Replay files at 25fps but coped well with 12.5fps. A Risc
PC is a must here, but even then I had a few troubles with 25fps. You
must forget multitasking if you want to get out good results, and make
sure that you have at least 20Mb free on your hard disc to save the
resulting file. Also, you must use a fast hard disc, because some of the
older slower hard discs will not keep up with the input and some rather
strange results can occur.
8.2
To capture the images, you play the video source in a window on your
desktop. Along the top of the window are the normal video style
controls. To save static images, it is just a matter of clicking on the
record button, the display will stop for a few seconds and the picture
will be saved.
8.2
To capture Replay files, the procedure is exactly the same except that
Érecordæ starts the recording and you need to click on Éstopæ to stop
it. The screen display stops during the recording (with a periodic
update), so it can be a bit hit-and-miss as to how much you record.
Bearing this in mind, it does seem odd that there is no way of editing
the film before you use it in your application.
8.2
On test
8.2
To put the card to the test, I took my video camera out around Norfolk
to capture a number of images and Replay files for some multimedia
programs I am writing. Firstly, I captured the local wind turbines,
which translated into an excellent Replay film, even though the subject
was white against a background of sky. Then I visited ten historical
churches to capture both features and an overall picture of the church.
8.2
Once connected to the A5000, I then used grab choices and started
playing the video in a desktop window. I then had to take around fifty
static images out, but once I had specified the directory to save, it
was just a matter of clicking on the record button any number of times
because each time you save a picture the computer adds a number suffix

To capture the Replay sequence was more difficult, as I couldnæt tell
the exact point at which I wanted to finish. Then I hit on the solution:
I recorded the video onto my VCR and leaving that attached to the TV, I
connected up the computer to the VCR. I then played back the recording
and watched the TV and just used the computer monitor to press the
buttons. I didnæt see any degradation in the picture quality but Iæm not
very good at judging this.
8.2
I also tried capturing a series of images direct from a pre-recorded
tape in the VCR Ö these were excellent. The only failure I have to
report was when I tried recording from my TV via the VCR. The picture
quality was bad, but I think this was due to the bad reception we get
out in the wilds of Norfolk!

On the monthly disc there are a series of static images that I have
captured using the Eagle card and a normal VHS camera. These images are
only 256 colour as they need to be distributed to readers with older
machines but the results using a Risc PC and 32 thousand colours are
outstanding. If anyone wants a copy of these larger files, just send me
a disc and return postage.

Sound as well
8.2
The Midi port is the only one supplied with a lead, the board end has a
15 pin D type socket with three colour-coded 5 pin DIN sockets on the
other: Midi in, Midi out and Midi through. Once these are connected, you
can use most Midi software such as Rhapsody, Serenade or even Maestro.
8.2
The stereo DIN socket allows your computer to record sound and to export
it via an amplifier. Certainly, some of the Digital Symphony tracks
sound very good when put out via a hi-fi. To record sound, you need to
connect a microphone to an external amplifier and then connect that
amplifier to the computer.
8.2
To manipulate all this sound, AudioWorks is provided on two discs along
with the manual. I have very little to add to the review by Brian Barr
in Archive 7.7 p57, except to say that it was a delight to use. One
feature I did find very helpful was the ability of AudioWorks to strip
out sound samples from Stracker tunes. You just take the tune and drop
it on the AudioWorks icon and you can add a few more sound samples to
your collection.

Conclusions
8.2
Computer Concepts and Wild Vision have had a reputation for establishing
their software and hardware as the standard against which others are
judged. Well, they have done it again! The Eagle card will become the
standard because it is far and away the best method of producing
material for multimedia. The card has something for everyone: the
musician will love the ability to capture just about any sound you could
want, along with the Midi interface, the graphics fan will be able to
capture just about any picture he could want, and DTP users will benefit
from the same ability. Whatæs more, the whole lot is on one expansion
card.
8.2
The Eagle card costs ú380 through Archive and although that may sound a
lot, you should consider that a Midi card would set you back about ú70,
a vision digitiser another ú100 or so, an Oak Recorder about another ú60
and AudioWorks adds another ú50. Then remember that even an A5000 would
be running out of expansion slots with this little lot. The Eagle card
is a remarkable buy.
8.2
Computer Conceptsæ advert depicts an eagle with the caption Ésoaring to
great heightsæ but I suggest that they replace it with the Lunar Module
of Apollo 11 and say that the Eagle has landed Ö in my view, itæs
certainly out of this world!ááAá
