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.

File contents
*INFO Compiled by Dave Lawrence and Dave Acton Run this application to open a directory containing the programs from this month's *INFO column. Note: The following files are NOT suitable for Risc OS 2: DTwelcome+, Templates. ElasticNet is a graphical simulation of an elastic sheet. If you click Select and move the mouse, the sheet will be stretched, and will then spring back to shape. The program implements a neural network to create the effect. Creeper, M�tro and Kalejdo are all graphical demos. CropCircle, Granite and Granite2 are one-line graphical demos. The DTWelcome+ directory contains a module to enable to change the initialisation message on Risc OS 3. The module should be loaded before the desktop is started: see page 99 in the magazine for more details. FreeMem is a bonus item, and when run displays the amount of memory on the Free slot on the iconbar. For more information on the application, read the help file by clicking Menu over !FreeMem and choosing the 'Help' option from the 'App.' submenu. Rotate demonstrates fast sprite rotation. When it is run you are asked whether feedback should be used. If the feedback option is not chosen, then the program looks for a sprite called rot_pic in the CSD. If this is not present, then an error will be given. If feedback is chosen, then no sprite is needed. NOTE: If you have Risc OS 2, then make sure that the screen memory in the Task manager is set to at least 160K before running this program. Also, if you have a 1Mb machine, you will need to quit everything before running the program, as it takes up almost all the memory in a 1Mb machine. SharedCLib contains the source for a module which accesses the Shared C Library from assembly language. You should load the module SCLmod before running any of the programs in thie directory. The two programs demonstrate the module's searching and sorting calls. The source for the module is in SCLsrce and the SCL directory. If you wish to recompile the module, double-click on ThisDir first to set the CSD correctly. NOTE: If you have Risc OS 2, then you must load the CLib module before running these programs: it can be found in !System.Modules on your Applications Disc One. Templates is a file to replace the templates file for the Configure application in Risc OS 3. See page 99 in the magazine for details on installing it. Finally, the EightBit directory contains programs for use on the eight-bit BBC range only. The programs are included here for reference. For more details about the programs in *INFO, see page 95 in the magazine. � Copyright BBC Acorn User 1993
