L/+UPDAT1
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 All,
I don't know how many of you are actually using the Mode 0
screen editor I submitted in a previous issue.You will be glad to hear
that the new version is currently on the top of the 'programs to
rewrite' pile.
So far I have converted to machine code the following time critical
parts,which used to make it quite obviously painstakingly slow:
1.Locate pixel on screen by sending X in the range 0 to 639 and Y in the
range 0 to 255 and converting that to a screen memory location.
2.Scan keyboard and move pixel.
The only remaining parts are:
1.Drag box
2.Save innards of box to disk
So keep your eyes out in future EUG's for the result.
