Harrison/Letter
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 AcornUser,
Here are 5 programs which I have written and am submitting for possible publication in Star info, a description is given below.
Yours Sincerely,
Tom Harrison (age 14)
Description:
Avoid: - 1K game
A 1K (Well actually 1022 Bytes, but who's counting (except me)) mouse controlled game in which you have to avoid yellow things that fly in from the edges of the screen. Its (I think) a totally original game. I can survive a 1 min 30 second game, but on a multi-scan monitor the game runs faster and becomes harder. (I wrote it on a boring old monitor but it is fully compatible)
Pipes: - Nice things that grow
This prog draws lines of circles which grow and branch while it cycles the colours. Pressing the space bar once halts the growth, and pressing it again continues (This is useful on slower speed computers which may slow down the colour cycling when it is also growing).
Shells� AND Shells� - 1 Line programs
These progs just draw yellow pretty things! I wrote these programs after seeing "Shells" in the Nov. '96 Star info, I think that the programs here are intresting variations on the idea.
Spiral - 1 Line program
!!!WARNING!!! - This program uses triangles to draw a spiral then cycles the colours. Excessive use may lead to premature headaches and feelings of giddyness. Just load the program and type a number, examples are given.
