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.

Customising the electron character set
______________________________________
Have you ever wanted to produce a more interesting screen
display by using different letter styles?
There are several ways in which you can. One way is by
installing a rom containing a font, e.g. Charrom which
contains twelve new fonts. Another way is to create your own
fonts by using one of the font designers available.
There are several font designers available through the PD
libraries that do the job very well, two of these being:
The Boofont font designer and the
Andrew Pepperell font designer.
Both of these designers work on the BBC but only the Boofont
designerworks on the electron.
Once a new font has been created and saved to disc, the code
has to beconverted for it to be usable. As the code for each
character was saved,the individual parts were joined together
to form one string of 24bytes.
0 0 0 0 1 1 1 1 15
0 0 0 0 1 0 0 1 9
0 0 0 1 0 0 1 0 18
0 0 0 1 0 0 1 0 18
0 0 1 1 1 1 0 0 60
0 0 1 0 0 1 0 0 36
0 1 0 0 1 0 0 0 72
0 1 0 0 1 0 0 0 72
If the character is defined as above then the saved character
string is:
015009018018060036072072
The conversion program is supplied on the disc with the
filename"Convert" which takes the file as named in line 20 and
the name of the converted file in line 30. The convertion
takes about 45 seconds and once converted the font file can be
*RUNned. Once the new font is installed in memory it stays
until break is pressed.
If you wish to use the new fonts on the electron, extra memory
has to be set aside for the character definitions. So to
properly install the new font type the following:
*FX20,6
*RUN fontname
PAGE = &1900
If you choose to use Andrew Pepperells font designer, the
output produced is of a different form and because of this a
different conversion method is needed. The program "Convert2"
is for use with this designer and when converted the font can
be used as before.
