These programs were distributed by Commodore Business Machines Canada as public domain in the Commodore Educational Software collection dated 1983. They run on the following computers: BASIC 2.0 PET, BASIC 4.0 PET, 8032 CBM (with an 40-column emulator program) and the Commodore 64. The programs seem to be slightly updated versions compared to the collections at http://www.funet.fi/pub/cbm/pet/edu/Canada/ uploaded by Olaf Seibert.
