Star Trek was a very popular game on early microcomputers and minis, and lots of versions existed at one time. The "standard" was originally written in BASIC for a Sigma 7, then rewritten in Hewlett Packard BASIC, by Mike Mayfield in 1972. It was included in the HP library early in 1973. Most versions are BASIC or FORTRAN adaptations of this, which was based on an 8 x 8 galactic grid. David Ahl tr
