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.

Kempton
Germany
Dear Mr. Donnachaidh (or may I just say dear Gus?)
I'd like to rejoin EUG.
I am also sending you a leaflet about Kempton unfortunately
it's only in German but I can send you an English version
next time. (So that you'll know where about I stay here.)
I am a student and so unfortunately don't have much time
however I want to bring my Electron back into action again.
I also have a BBC Master 128 with 80186 Coprocessor (1MB
Ram) and a 386 PC here in Kempton just infront of my typing
this letter. I'd like to put my Electron into a PC case.
However the trouble is how to make a PC-Keyboard interface
for it if I don't know the signals produced by an Electron
keyboard?
I'd also like to know how to make an Interface to connect my
Electron to an S-VGA monitor. (I have instructions to
convert it to EGA from an old Micro User but not VGA which
is quite different I think.)
Can you ask via the EUG disk if anyone can help (I remember
someone selling his Electron beeing in a PC-style case even
with a hard disc!)
Please help
Yours sincerely
Oliver
I DON'T WANT TO PUT A DAMPER ONTO YOUR INTERESTING IDEAS
ESPECIALLY SINCE SOMEONE IS ONLY GOING TO TELL ME THAT I'M
WRONG BUT THE PC KEYBOARD IS INTERFACED TO A PC USING A
SPECIAL TYPE OF SERIAL INTERFACE WHICH ISN'T ON THE
ELECTRON'S KEYBOARD SINCE THE ELECTRON WASN'T DESIGNED FOR
IT. NOW IT SHOULD IN THEORY BY PERFECTLY POSSABLE TO MAKE
SUCH AN INTERFACE FOR THE ELECTRON. THE SIGNALS PRODUCED BY
THE ELECTRON'S KEYBOARD ARE A SIMPLE MATRIX I BELIEVE WHERE
IF TWO PINS ARE CONNECTED TOGETHER A KEY IS ASSUMED BY THE
MAIN COMPUTER BOARD TO HAVE BEEN PRESSED.
S-VGA I THINK NEEDS SOME TIMING SIGNALS AND A NUMBER OF
OTHER SIGNALS WHICH WOULD EACH NEED TO BE EMULATED. HERE IN
THE UK THE SECOND HAND MARKET IS QUITE LIVELY AND I THINK
YOU WOULD HAVE NO PROBLEM SWAPPING AN S-VGA MONITOR FOR A
GOOD EGA. IS THE MARKET AS GOOD IN GERMANY? SINCE YOU HAVE
DETAILS OF CONNECTING AN EGA MONITOR COULD YOU SEND THESE TO
US HERE, SEVERAL MEMBERS WILL BE INTERESTED.
HARD DISKS ARE QUITE EASY TO CONNECT TO THE ELECTRON ONCE
YOU HAVE THE RELEVANT INTERFACES AND SOFTWARE. THE DEMAND
WAS THERE SO PEOPLE MADE THE INTERFACE, I MAY BE WRONG BUT I
HAVEN'T HEARD OF ANYONE MAKING AN INTERFACE FOR AN S-VGA
MONITOR
THANKS FOR THE LEAFLET. CAN YOU TYPE IT ONTO A DISK IN
ENGLISH AND SEND IT TO EUG?
