L/WELLS1

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.

Dear Gus,

While playing about with my Electron I discovered something quite strange
- if at the '>' prompt I type in a lot of numbers separated by commas (eg.
5,9,2,6,4 and so on randomly) untill the computer beeps, them press
RETURN, my computer changes screen mode from 6 to 4 , makes a noise and
switches the cassette motor on. I was wondering if this happens to anyone
else's computers and why it happens?

Yours faithfully,

John Wells
