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.

JULY 1984 ********* ARTICLES ~~~~~~~~ Introduction to Programming (Part Six) - by Pete Bibby. This article actually claims to be Part Five, but as we know that appeared in the previous month's edition so someone done a silly somehow! FOR...NEXT loops were under scrutiny this time. Let Your Text Walk Tall - by John Woollard. You may recall that in a previous "E.U. Index" column I said that there would be times when it would be hard to decide if an item should be classed as an article or a listing, well this is one of those. There were three different listings (including one in Machine Code) for creating on-screen double-height text, each of which were discussed in a detailed article. Classroom Companions - by Phil Tayler. Phil (or "Old Poo Pants" to his pupils) was a teacher explaining how the Elk was used in conjunction with the Beeb at the school where he taught. Graphics - by Mike Macmanus. The graphics cursor plus the MOVE and DRAW commands were put through their paces. LISTINGS ~~~~~~~~ Solitaire - by Russell Cartwright. Thanks to our trans-Atlantic cousin's habit of using the name "Solitaire" for the card game "Patience" I never know if I'm supposed stack playing cards in their suits or clear a board of counters. This game is of the latter variety. Sounds Exciting - This time you got:- Too many Chocolates, Dog Whistle, Alien Laser, Overload, Air Leak, Dizzy Daleks, Percussion. Times Table - by J.C. Curtis. 1X2=2, 2X2=4 3X2=6 .... get the idea?! Guess the Word - by Pete Davidson. Like "Hangman" but without the capital punishment. Impossible Triangle - by Phillip Rasmussen. Graphics demo wherein a 3D triangle was drawn with impossible joints at the corners - rather like those used by modern double-glazing companies. Golf - by Roland Waddilove. Rol's at it again, this timeletting you decide how hard to wack your balls... Bank Account - by Ken Smith. A simplified Spreadsheet to keep a check on your finances. Wish I had enough money to need it. Casting Agency - More modes of transport:- Oil Tanker (lorry), Off-road Pick-up Truck, Loco and Tender, Paddlesteamer, U-boat, Battleship. Chartist - by J. Willington. Produced 3D Bar Charts from data input by the user. Volume-Area-Trigonometry - by Richard Rennie. Program to calculate things like the volume of a sphere and lots of other clever mathematical things that I can't begin to understand. **************************************************************************
