According to the readme of the DOS game, the original program was written by Bruce N. Baker on a DECsystem 10 (a DEC PDP-10 with TOPS-10 operating system) at Eastern Montana College in Billings, Montana. Some significant modifications were made by Arron Barnhart, but no further development was done for a long time.

In 1987, Baker translated the game from its initial "primitive" BASIC dialect to Desmet C and assembler, and later converted it to pure Microsoft Quick C, beginning with game version 2.0. The game was then extended, and the auto-mapping feature finally added in 1991.
