MikeC/Software/TEST-B
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.

; PROGRAM TO TEST OPERATION OF EMULATOR
; By Bill Jeffs
;
; Checks operation of the interrupts from PortB and RTCC
; Operate switches PortB, 4 to 7 to generate interrupt.
; Interrupts generated on the lo-hi and hi-lo transitions.
; Detection of operation confirmed when PortA, 1 to 4 LEDs are on.
;
; PortB,0 a hi-lo transition Toggles PortA,0 LED
; PortB,2 LED toggles on each timeout of the RTCC
