- More in the FPD saga...
-
- TMON won't work with the FPD screen running. I called ICOM, and they
- said they don't have an FPD and therefore they don't support it, call
- back in a month. :-(
-
- The screen itself is very nice. The letters are a bit smaller, and
- there is one major ergonomic failure: neck strain. Yup, I'm not used
- to tilting my head down to read something. I've already got two
- telephone books under the monitor, it looks like I'll be going to at
- least 3.
-
- The biggest problem is with software that doesn't like windows bigger
- than their documents. Also, the first two Mac word processors don't
- work too well with page-sized windows. Luckily, the next crop,
- including MacAuthor, WriteNow, and HabaWord, all work fine.
-
- Computer Ware in Palo Alto has the FPD on their price list, but I asked
- -Radius
- if other people would have to send in their Mac like I did, and they said
- -that
- for the time being, that's how they're handling it. (I asked before I saw

- I have no alarm clock as a DA. I wonder if the startup code checks
- the value of a global (usually set by the alarm clock) to determine if
- a beep is appropriate. Changing system files usually fixes the

-
- Yes, it does work with MacDraw, MacWrite but not with Paint or
- FullPaint. I have tried MaxPrint on my DataFrame and it works well
- with everything (so far). I don't like the way it works as much as I
- like SuperSpooler, however. In MaxPrint the document begins to print
- from the spool almost immeadiately. This means that the spooling
- operation (i.e. the time during which the Pause, Continue, Cancel
- dialog is on the screen) takes much longer, since the spooling is
- competing with the printing. In SuperSpooler the printing stops while
- the document is spooled so that you are returned to the program much
- faster. I like this much better. After all, if I am spooling the
- files I want to have them spooled quickly and then get on with it,
- rather than fight with the printer for CPU time. Let it print when I
- am on the phone or doing something else. -Doug

- Subject: disk initialization bug?
- Date: 9-OCT-04:10: Bugs & Features
-
- Lately i've been getting a strange bug with my floppy drives. the
- environment is a 512K Mac with MacMemory 1.5 MB add on, HD20, 128K
- ROMs and two 800K drives. the HD is about 10-11 Meg full.
-
- on sporadic occasion, the drives refuse to acknowledge a disk
- insertion, or cannot read a diskette that was running perfectly
- happily ten seconds before. the standard disk initialization dialogue
- goes up, I click eject, nothing happens. The only recourse is to
- reboot the machine, holding the mouse button down for a forced eject.
- this happens randomly on both floppies. Same disks will read and
- write perfectly the rest of the time. similar problems happen also
- randomly when I call Erase Disk functions.
-
- has anyone else seen this problem? i ran a set of hardware test
- programs I have on the machine and they report nothing unusual in the
- drives, RAM,etc.
-
- would certainly like to hear about such.
-
- thanks. gdg
-
- ps:: in a moment of backup frenzy, I decided to do a test on mainstay's
- FLA hard disk backup program: I backed up the entire HD20,
- reinitialized it, and then restored the whole thing. FlashBack
- worked flawlessly, did a reasonable job of backing things up
- neatly (11 meg onto 14 800K floppies in 18-20 min, same restore)
- and I recovered nearly a meg of space in the process. thought
- you'd like to know; I have no connection with mainstay other than
- now being sure that I will recommend their product to my users
- group and purchase the copy of it loaned to me to test by my
- dealer.

- Subject: A better disk performance analyser...
-
- Seems to me this test will more reflect the presence/size of the cache and
- -the
- degree of file free-space fragmentation than the performance of the disk
- subsystem itself.
-
- One who has already purchased a particular disk drive knows its usable
- performance through use. The problem is to compare competing candidate
- subsystems on a basis which eliminates confounding variables such as cacheing
- and the distribution of file free space.

-

- > disk, e.g., non-ejectable [from the information returned by PBGetVInfo]?
-
- If you really want to know whether the drive is marked non-ejectable,
- you have to access the drive queue element. However, some disks which
- are for most intents and purposes "hard" are also ejectable, e.g.,
- Bernoulli Box volumes. It might suit your purpose to observe whether
- or not the drive number is 1 or 2 -- internal or external floppy. The
- drive number is returned by PBHGetVInfo, but not by PBGetVInfo. If
- HFS is not present, you'd need to walk the VCB queue instead of using
- PBGetVInfo in order to get the drive numbers. If you need to access
- the drive queue element, the drive number would be the key to match
- against when walking the drive queue.
-
- Another clue is the size of the volume, ioVNmAlBlks*ioVAlBlkSiz +
- -ioAlBlSt*512.
- If it's less than or equal to 800K, then it's either a floppy or a small
- partition of a hard disk.

-
- Their claim is nonsense.
-
- Here's a wild guess as to what's causing the problem. Most SCSI disks get
- themselves mounted by setting the dNeedTime bit in the driver when the driver
- is first opened, so that the driver will get called when the first
- -application
- calls SystemTask the first time. If the driver neglects to reset the
- -dNeedTime
- bit, it will get a call on every SystemTask forever after. I don't have
- a lot of confidence in this theory, but it might be worth mentioning to
- -Rabbit.
- If you're at home with a debugger, you could test the theory by breakpointing
- on the driver's Control entry point at a time when most any application is
- just idling. If Control is entered, there's something wrong, and if $1A(A0)
- contains $41, the theory is confirmed.
-
- The DCE handle is at the address contained in $11C, plus 4*SCSI ID. The
- -first
- long in the DCE is the driver address. The word at offset $0C into the
- -driver
- plus the address of the driver is the Control entry point.

-
- Since nobody is mentioning anything about it I thought I'd give you a
- few of the new features that will appear in the new version of
- PageMaker comming ou at the end of this month, begining of November.
-
- - Kerning - Leading with special FFT files - Automatic hyphenation - Built-in
- dictionary - Recovery from temporary files
- ( if your file crashes ) - Inclusion of Postscript
- ( You can even put a PageMaker page inside a PageMaker document ) - Better
- screen display representation - Improved support for bigger resolution
- -devices
- - Improved publication size of document
- ( you'll be able to create PageMaker documents of 120 pages )
-
- That's it for now, more when we finished playing with the beta.

- From: MACMAG (13661)
- Subject: RE: PageMaker 2.0 (Re: Msg 13654)
- Date: 11-OCT 02:03 Business Mac
-
- Ok here's the goulash in more details:
-
- PageMaker 2.0 will be able to read MacWrite, Text-only, Microsoft
- Word, MacPaint MacDraw, Microsoft Works, MacDraft, FullPaint, Cricket
- Graph, PICT, Cricket Draw, and Postscript files via the Place command.
-
- Hyphenation
- -=-=-=-=-=-
-
- PMaker 2.0 will support 3 methods of doing hyphenation: Automatic (which will
- be available from a 90,000-word dictionary supplied by Houghton-Mifflin
- -Comp.).
- You will be able to add 1,000 words of your own choosing. There will also be
- prompted hyphenation for your own personal entries, and last there will be
- the standard manual discretionary hyphens by keyboard (a la Microsoft Word).
-
-
- Kerning
- -=-=-=-
-
- There will be two forms of kerning. Automatic pair kerning will work with
- pre-defined pairs of characters established by the font manufacturer. Manual
- kerning is the other, via the keyboard, to loosen and tighten the space
- between any two letters.
-
- Spacing
- -=-=-=-
-
- There is now a major rewrite over spacing capabilities. This includes word
- spacing (inter-word spacing). For justifies text, the user has the option to
- control the maximum and minimum amount of spacing.
-
- Letter spacing is the inter-character spacing. This automatically ajusts
- the space between letters within a line of text to eliminate excess white
- space.
-
- Last, there's paragraph spacing. You'll be able to specify additional space
- before and after paragraphs in half-point increments.
-
- Leader Tabs
- -=-=-=-=-=-
-
- PMaker 2.0 now supports leader-filled tabs. This feature will fill the space
- preceeding tabs with thin-space periods, dashes, underlines, or user defined
- leaders up to two different characters.
-
-
- Fixed Spaces
- -=-=-=-=-=-=
-
- Supported are em-space, en-space, and thin-space characters.
-
-
- TEXT
- -=-=
-
- With a single menu or keyboard command, a portion of text can change from
- upper case to lowercase to all caps to small caps or even strike-thru
- -letters.
-
-
- Larger publications
- -=-=-=-=-=-=-=-=-=-
-
- With a new numbering systems, 2.0 creates files of up to 128 pages. Combined,
- you can have numbered pages of up to 9,9999 pages.
-
- Interactive facing pages
- -=-=-=-=-=-=-=-=-=-=-=-=
-
- The five interactive viewing sizes can be displayed as single pages or facing
- pages. With a facing page view you can work on a double-page spread without
- having to shift back to left/right pages.
-
- Lines
- -=-=-
-
- There are new line styles such as half-point and reversed. Half-point fills
- the gap between the hairline and one-point line. With the reverse command
- any line style will reverse white out of black.
-
-
- Column Width Sizing
- -=-=-=-=-=-=-=-=-=-
-
- You can now resize the lenght or width of a column by dragging the mouse.
-
- Text editing
- -=-=-=-=-=-=
-
- Editing can now be done through keyboard shortcuts. There are also cursor
- control keys for text modification.
-
-
- Selection
- -=-=-=-=-
-
- You now have the ability to select either an entire story or all the objects
- on a page with one command. Selecting an entire story allows you to make
- global changes such as text attributes or point sizes for the whole story.
-
- Fast Move
- -=-=-=-=-
-
- Text blocks can be moved quickly on screen by pressing the mouse. This way
- you will drag a box outline of the desired object. If this isn't suitable,
- by pressing the mouse down a little longer, you will see the complete image.
-
-
- Scanned image support
- -=-=-=-=-=-=-=-=-=-=-
-
- Postscript graphic files can now be placed in PageMaker where they can be
- scaled and cropped. If a screen image of the graphic is included with the
- PScript file, it is displayed when the file is placed in PMaker. Otherwise
- no representation will appear. A box outline representing the exact size
- will otherwise appear. You can even place a PageMaker page in your PageMaker
- documents!
-
- High resolution scanners that support the standard Tag Image File Format
- -(TIFF)
- such as the Microtek, DEST, Datacopy and others will be fully supported.
-
-
- Display enhancements
- -=-=-=-=-=-=-=-=-=-=
-
- An image that had been cropped to fit a given space can be scrolled to expose
- a different part of the original image.
-
- Screen positioning of line endings is an exact representation of their
- printed version.
-
- Accuracy of rulers, line styles and positioning has been improved for every
- page view.
-
-
- Spooling
- -=-=-=-=
-
- PageMaker 2.0 will support spooling using Apple's new print spooling
- -protocol.
-
- Printing enhancements
- -=-=-=-=-=-=-=-=-=-=-
-
- PMaker will calculate ideal enlargements and reduction factors based on the
- printer's resolution, for bit-map graphics. This will iliminate irregula-
- rities in bit-maps with regular patterns.
-
- There will also be automatic tiling for documents that run larger than 8 1/2
- by 11. Automatic crop marks on final documents will be printed where it
- should be trimmed. You'll be able to print pages in reverse order and collate
- pages.
-
- The ImageWriter will be part of the deal in the way of better support and
- taking advantage of it's unique features. Text and Graphics output on the
- ImageWriter can now more acurately match LaserWriter output.
-
-
- Overall
- -=-=-=-
-
- You'll see over performance improvents in text editing, save, goto page,
- -open,
- and close commands, and the support of large screen displays.
-
- Crash
- -=-=-
-
- PageMaker now has a built-in mechanism for crash recovery. damaged files can
- now be restored to the state of the last turned page.
-
-
- Voila, hope this wets your appetite. That's all for now, I'll keep you all
- informed on comming attractions such as SuperPaint and Solo.
-
- Ciao for now.

-
- Control of MICAH was recently acquired by a well-funded company. The new
- majority owners decided that a chapter 11 filing was best for the longevity
- -of
- MICAH. The reasons for this are tied both to general financial difficulties
- that MICAH had gotten into pre-acquisition, and to a specific and serious
- problem that had arisen with one key vendor which threatened MICAH's
- -existence.
- The foregoing is what I am told (I am a contractor to MICAH). The new
- -majority
- owners appear to be confident in MICAH's product and market position, and in
- their own ability to provide the sound financial management that had been
- previously lacking. Turn-arounds seem to be their specialty.
-
- I was disappointed to find out about the chapter 11 filing, because (a) it
- -does
- complicate the business dealings with the company of vendors such as myself
- -for
- awhile; but more important (b) most people incorrectly interpret chapter 11
- -to
- mean "belly up," and I thought that would hurt MICAH's marketing efforts
- -among
- end users. However, the new majority owners still thought that chapter 11
- -was
- on balance the best course.

- Can you get serial interfaces on those printers? Seems like the only problem
- would be an appropriate printer driver software file that understands the
- control characters used.

-
- Make sure it has the resLocked attribute in the resource file. The segment
- loader will load CODE resources that are not resLocked at the top of the
- -heap,
- which, in the case of CODE 1, occurs before you've called MaxApplZone -- so
- -the
- top at that time will become "1/3 of the way" later.

- One thing that I haven't seen noted in the fan discussion was brought
- up a while back on CompuServe. It seems that almost all the air
- pulled into a stock Mac for cooling comes from the _front_ vent, and
- not from either of the side vents. This implies that one should take

- Date: 10-OCT 22:08 Programming Techniques
-
- Be aware that when your code is running as an INIT under the INIT 31
- -mechanism,
- that you are a Handle via an open resource file. If you use SetAppBase, which
- destroys the Application heap, and consequently, the Resource Map, you are
- -left
- dangling in mid air. If you indulge in App heap or memory related size
- -changes,
- you would be better off to do a _RecoverHandle , _DetachHandle to preserve
- -the
- Mac memory managers view of your code.
- I hope this helps someone!

- I'd imagine also that a bug related to that could remain hidden for a good

- longer than it would in a normal application, since the environment during

- running of INIT's is much less chaotic than it is in an active application.

- Date: 11-OCT 15:53 Programming Techniques
-
- I first encountered this problem when I blindly put INITs in a
- separate file, setting the file type to INIT so that the INIT31
- mechanism would execute them. I liked the idea - no more cut and paste
- with Resedit, and I could deactivate an INIT by just moving the file
- out of the System folder ("Blessed folder"). The problem INIT was
- StartupDesk -- it is quite dramatic,as it expands the SYstem heap, and
- then allocates a screen buffer in the recently expanded heap. However,
- as the INIT's Resource map entry was in the App heap, it was zonked by
- the _SetAppBase call, and so the NewPtr promptly allocated mem over
- the top of the executing code. The solution is to do a _RecoverHandle,
- _DetachHandle at the front of the INIT.

- I would like to solicit some suggestions/comments from any hard core
- software developers (or anyone else with an opinion, for that matter).
- I'm manager of software at a small (~80) company involved in digital
- voice and telecommunications. We currently do all our s/w development
- (try not to laugh) on a PDP 11/70 running UNIX V7. There are about
- 35-40 users(!) connected to the system, which is also used for word
- processing, spreadsheets, electronic mail, etc. I will soon have the
- opportunity to replace this antiquated pile of junk with a new system.
- I havenUt had much time to research it, but right now there appear to
- be 3 leading contenders: Sun, Apollo, and DEC. I am currently heavily
- leaning toward installing a network based on Sun's workstations. If
- anyone has any experience with any of these, I would be very
- interested in hearing about it.

- Steve, do you know anything about the FX/20? How does it compare
- against the Micah external and the DataFrame (XP or otherwise?). I'm
- "evaluating " to see if I should carry it in my store (currently
- carrying Dataframe). The simple observations that I've made are that
- the laser spooler seems nice (though prone to hang it seems), but the
- price is higher with only a 3 month warrentee (extension to 1 year for
- $200), it has a plastic case, is too big to fit in the MacPacks
- (Linebacker) carrying cases I favor, and is rather loud.
- Specifically, HyperDrive seems to have a poor reputation for service
- and reliability...is that likely a function of the internal drive
- alone or is it likely to carry over to their external drives? (You're
- not omniscient, of course, but I respect your opinion...fool that I
- be!). Any comments you might have are appreciated.

- Subject: code segments
- Date: 11-OCT 16:12 Programming Techniques
-
- I have a question about code segments and loading, which results from
- the fact that until just recently, none of my programs had ever
- approached the 32K limit. The way I understand it, a given segment
- (other than CODE 1) is not loaded until a routine in that segment is
- needed. Does that mean that if I want all the segments loaded at
- launch time, I have to issue a series of LOADSEG calls in my
- initialization code, or is there some flag I can set which will do
- this for me automatically?

- We need the help of anyone on this one! Several weeks ago the campus
- cafeteria began using a Mac on loan from Apple to assist in menu preparation.
- While the program, Dinner At Sixish, is supposed to suggest menus that
- -promise
- a healthy combination from the basic food groups, we have been eating only
- Tuna Noodle Casserole since the unit's installation! Since this includes
- lunch, dinner and even breakfast you can imagine the near riots we face three
- times each day.
- Does anyone know if Dinner At Sixish actually contains recipes for
- -anything
- besides Tuna Noodle Casserole, or if we have a bad copy of the program?
