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.

PRES E00 & ABR ~~~~~~~~~~~~~~ By Richard Dimond If you have 32k SW RAM, preferrably battery backed (ABR), this can be very useful for ADFS users as it enables the use of the full memory and avoids the 'bad sum' errors and the need for using Ctrl/Brk after a program has downloaded. It is supplied on a disc together with all the Welcome programs and utilities and needs to be BOOTed up into SWR. It's main disadvantage is that if used with the ABR cartridge, this has to be removed when using VIEW. The ABR has a means of locking in ROM images. This is supplied on the ABR with six other utilities and these need to be transferred to disc or tape before the cartridge is used. I have found that the locking does not seem tp work with the PRES E00 and so I do find that the code can get corrupted. It is easily loaded up again provided that the ABR is cleared. This can sometimes be difficult as there is no way of temporarily disconnecting the battery and the only way seems to be by removing and replacing the cartridge while the power is on - rather a brute force method!! Has anyone a better way round this? **************************************************************************
