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.

Help file for Swirley - 892 bytes of hand written assembler - and a 5K look-up table! ===================== �Graham Stratton, 1998 - Requires mode 28 This useless program generates a lens which then warps the picture underneath it. The picture MUST be 640*480 and in 256 colours. It really needs a much faster bus than the current Risc PC can offer, so if anyone would like to give me a Phoebe I will endeavour to make the program work on that! The picture must be placed in the application directory, and the sprite must be called swirl and the spritefile called image. Once you have created this file, play around with it. A good one to use is the tiger picture (slideshow - sa01). To convert any image for use with this program follow the following procedure: 1 - Load ChangeFSI 2 - Change to a 640*480 mode (27/28) 3 - IconBarMenu - Sprite - 256 colours, square pixels 4 - IconBarMenu - Scaling - Scale to fit 640*480 5 - Drag sprite to ChangeFSI 6 - Save sprite as "image" inside application directory 7 - Load sprite into paint 8 - Rename sprite "Swirl" 9 - Resave sprite file
