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.

Break Disable Utility v.2 *BREAK <ON/OFF> This routine enables a program to be kept running, even if <CTRL><BREAK> is pressed. It has been found very useful by teachers during school demonstrations etc. The <BREAK> key can be disabled using *BREAK OFF The <BREAK> key can be enabled using *BREAK ON (or use *FX247 0 to enable) It is essential that your program contains an ONERROR statement. The following is a simple demo program: 10 ONERROR RUN 20 PRINT" This is a demo" 30 IF INKEY(-1) THEN GOTO 50 40 GOTO 20 50 *FX 247 0 60 END Once this program has been entered type *BREAK OFF and run the program. Pressing <BREAK> will not stop the program but will carry out the instruction contained in the ONERROR statement. (To escape from demo press <SHIFT>) The routine is designed for a BBC model B or B+, and does not operate on a Master computer.
