The game was originally advertised for the OSI in the June 1980 Aardvark newsletter. (See Jason Dyer's blog for a bug-fix for the OSI version)
The original publisher, Aardvark, sold versions for OSI, TRS-80, 16K TRS-80 Color, Timex/Sinclair, VIC-20 13K, and Commodore 64. An August 1982 advert suggests the PET was also a supported platform.
The game was sold in Australia as Enterprise Escape for the SC-3000 computer by Grandstand Leisure. The original author was not credited.
Jim Gerrie has created a version of the game for the TRS-80 MC-10.
