The advert in Sync Magazine, Volume 2, Number 4 (July/August 1982), lists the available platforms at the time as Timex Sinclair, TRS-80, TRS-80 Coco, OSI, and Vic-20; and credits the game solely to Rodger Olsen.
The November 1984 Aardvark (British Intelligence) catalogue, also lists IBM PC & PCjr and C64 as platforms.
The later (1984) C64, TRS-80 Color Computer & PC versions featured graphics. The CoCo version was called 'Graphic Mars' and was programmed in assembly language by Roderick Smith.
The VIC-20 version is known as Mars Adventure.
The game was sold in Australia as Mars Adventurer for the SC-3000 computer by Grandstand Leisure. The original author was not credited.
Jim Gerrie has created a version of the original BASIC game for the TRS-80 MC-10.
