- Every Acorn Archimedes and BBC A3000 computer is supplied with a !System
- Application on the Apps1 disc, or hard disc. Within !System are stored a
- number of modules which various applications such as !Paint, !Edit and !Draw
- all share. The modules in !System extend the operating system and once
- loaded may be accessed by any application needing them. The first !System
- application 'seen' by RISC OS, can then be accessed by any applications that
- need to load any of the modules. The modules which Acorn supply are
- CLib(Shared C Library), FPEmulator(Floating Point Emulator) and
- Colours(Colour Translation Module). Since the release of the original
- Application disc one there have been numerous updates of the !System
- Application. Acorn have allowed third parties to incorporate !Systems with
- their software packages. Acorn have also released a new !System Application
- on the RISCOS extras disc(Please refer to BBC Acorn User January 1990 issue
- of details on how to obtain a copy of the RISC OS extras disc). The !System
- Application is structured as follows:
-
- !System
- |
- -----------------|----------
- | | | |
- !Run !Boot !Sprites Modules

- CLib Colours FPEmulator
-
- With all these different !System directories available it can become
- confusing as to which !System you should be using. The modules are written
- however to be compatible with earlier versions, and all that need be done is
- to ensure that you use the latest versions of each module. The best way to
- determine this is to check the date stamps on the modules.
-
- You enter the !System Application by holding down SHIFT while doubling
- clicking on the !System Application and then enter the directory Modules by
- doubling clicking on this directory. It is then possible to click with with
- middle button of the mouse over the window which contain the CLib, Colours
- and FPEmulator modules and by moving across the menu to the right of the
- word Display another menu will appear. The top three options will be Large
- icons, Small icons and Full info. By clicking on Full info, information
- regarding the files in that window will appear including the date when the
- files were created. If you check these dates against the dates in any other
- !System Application directories you may have, you can then see which is the
- latest version of the !System Application and ensure that all the copies you
- have on all discs are the same, thus causing less confusion in the future
- when undoubtedly newer versions will be released. Please note that third
- parties have also included some of their own modules into the !System
- Application so be careful not to delete these.
-
- When using the !65Host application from the RISC OS extras disc it is
- possible to create mini applications that boot themselves at the same time
- as starting !65Host. This has proven to be extremely useful for educational
- users who are booting BBC software into 65Host from networks. If you would
- like a copy of an application note explaining how to do this please send an
- A4 SAE to our Customer Services Department.
-
- We have a number of enquiries with regard to the new version of the PC
- Emulator and DR DOS.
-
- DR-DOS represents an alternative operating system to MS-DOS. The product,
- developed in the UK by Digital Research, is claimed to be effectively 100%
- applications software compatible with MS-DOS 3.3. The operating system
- includes a built-in Help system which will be of value in the Learning Curve
- product.
-
- The PC Emulator version 1.33 has undergone a minor upgrade to 1.34 to
- accommodate operation with DR-DOS (as supplied with the Learning Curve
- package). Both versions of the PC Emulator continue to be compatible with
- MS-DOS version 3. Speed of performance and applications compatibility are
- essentially the same with either operating system or PC Emulator version.
- There is a small loss in workspace of around 25Kbyte with DR-DOS due to the
- added Help feature.
-
- People who wish to use their Archimedes or BBC A3000 systems for use with
- Open University courses will be pleased to hear that the PC Emulator has now
- been approved by the Open University for their computing courses in 1990.
- Course details are available from the Open University.
