The original "1985" version of the game was never published. A copy of the source code was provided to Mark J. Cox in the mid-1980s. Mark ported this code to Sharp MZ-80K and later to GWBASIC on the Amstrad PC1512.
In 2020, a version for modern Window and Linux PCs was produced by Mark J. Cox using the original source code, with the blessing of the original author.
