!AWFeb92/Goodies/Resources/ReadMe
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

System Resources - a new approach
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The model: There are two resource applications, !System and !Scrap.
!System defines System$Path (i.e. System:) which provides
indirection to the system modules directory. This directory
contains the Acorn system modules. Effectively this
directory is read only.
!Scrap defines Wimp$Scrap and Wimp$ScrapDir which provide
somewhere to store temporary files. Effectively, this
directory is write only.
!SysMerge is a utility which manages the updating of the new
!System as later versions become available. It is only ever
provided with the new !System.
The benefits: Previously !System was used as both a source for commonly
required (Acorn?) system modules AND a place in which to
store temporary files.
On networks this lead to there having to be a copy of !System
for each user so as to provide a place for temporary files,
therefore causing the unnecessary duplication of the system
modules. !Scrap allows each user to be provided with a place
for temporary files with a very small space overhead
and !System is only provided once as a central resource.
For the 'single floppy disc drive' user the problem is one of
frequent disc changes. This is typically caused by the
system resources (!System) being on one disc and the
application being on another due to limited space on the
latter. A disc change is therefore requested whenever a
temporary file needs to be created.
This problem may be overcome when it is understood that,
typically, an application will only need to download system
modules at start-up. Any run-time requirement is likely to
be for temporary file storage. Therefore, if !Scrap is
provided on the application disc, there will only be the one
request to insert the !System disc, when the application is
started.
The rules: i) Third party distribution of system resources will be
restricted to those modules which the application
requires for correct operation and cannot be assumed to
be easily available to the user.
The definition of 'easily available' may change in the
future, but is currently those versions as supplied with
the originally shipped RISC OS based systems.
ii) Users will be encouraged to have a 'system disc' which
contains their unique (to them) copy of !System.
Multiple copies of !System is discouraged and third
party 'single disc solutions' will not be supported by
Acorn.
iii) !Scrap may be viewed as public domain and distributed
freely. Users of 'single floppy disc drive' systems
should be encouraged to have a copy of !Scrap on all
discs and educated to double-click on it when a new disc
is viewed.
iv) !System is always distributed with !Scrap and !SysMerge
and the latter should be the only way in which !System
is updated.
v) A licence is required to distribute !System.
