Trivia
The Commodore PET/CBM version will also run on a Commodore 64 and Commodore 128 (in 64 mode).
Since this game was written in BASIC and had its source code published, it has enjoyed all sorts of conversions to niche systems and similar languages over its long lifespan, including one for the Sharp MZ-700, Adam Biltcliffe's version in Z-code, an adaptation to Cambridge Z88 BBC BASIC by C.L. Fenn, and ports to the HP-41, TI-83 and TI-89 scientific calculators by Dejan Ristanovic, Raymond Mullikin and Alex Morrise, repectively.
The game's source code was published on the July/August 1980's issue of the Recreational Computing Magazine.
