P/btext1
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.

Large Text Program
In June 1989, Electron User published two programs to
print outlarge banners on paper. One of these used the
Electron's built-incharacter set, and the other supplied its
own, using DATA statements. Ihave rewritten most of the
latter program, keeping the data from theoriginal, to print
messages on the screen instead.
Run the program and you will be asked to enter your
message. Thiscan only contain capital letters, and some
punctuation symbols (no lowercase letters, or numbers). If
you enter a symbol which the program doesnot recognise, you
will hear a beep.
Next, enter the position of the top-left corner of the
message, ingraphics coordinates (these run from 0 to 1279
from left to right, andfrom 0 to 1023 from bottom to top).
The width and height of the messageshould also be in graphics
coordinates.
You will also be asked for the gap between the letters,
in mode 4pixels. 8 pixels is usually about right (1 character
cell)
If you want to produce a message which is more than one
line long,build it up one line at a time using the LOAD/SAVE
facility. When askedfor the LOAD filename, enter the filename
you used for the SAVE filenamelast time you ran the program,
or press Return to start with a blankscreen. Similarly, when
asked for the SAVE filename, just press Return ifyou don't
want to save the result.
To load the screens back into the computer, use:
MODE 4
*LOAD <filename> 5800
You may want to use these large messages to create
autostereograms.See my separate article on how to do this.
They may also be useful intitle screens for games, or
headings for documents, etc. etc.
