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.

This application allows you to test transistors using the
IIC data bus and extra hardware:-
PCF8591 A/D and D/A chip
PCF8574 or PCF8574A Digital I/O chip
Multiplex and switcher circuits described in Acorn User 96
The transistor is subjected to various voltages and measurements are taken.
From this is deduced, the transistor type, its gain and its pinout. 00000000 49 49 43 20 54 72 61 6e 73 69 73 74 6f 72 20 54 |IIC Transistor T| 00000010 65 73 74 65 72 0a 43 6f 70 79 72 69 67 68 74 20 |ester.Copyright | 00000020 4d 69 6b 65 20 43 6f 6f 6b 20 31 39 39 36 20 20 |Mike Cook 1996 | 00000030 2d 20 4d 75 73 62 75 72 79 20 43 6f 6e 73 75 6c |- Musbury Consul| 00000040 74 61 6e 74 73 20 61 6c 6c 20 72 69 67 68 74 73 |tants all rights| 00000050 20 72 65 73 65 72 76 65 64 0a 20 20 20 20 20 20 | reserved. | 00000060 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | | 00000070 20 20 20 20 20 20 35 20 48 65 6c 6d 73 68 6f 72 | 5 Helmshor| 00000080 65 20 52 64 2e 20 48 61 73 6c 65 6e 67 64 65 6e |e Rd.
