Star Trek

Star Trek is a text-based computer game that puts the player in command of the USS Enterprise on a mission to hunt down and destroy a fleet of Klingon warships. Written in BASIC, it was widely distributed and ported for many minicomputer and mainframe systems. The game was non-graphical and was played out visually by printing each successive screen following each player command. On early machines, this was printed to a printer, which resulted in a lot of paper being used. (wikipedia.org)
