A niche mainframe game from 1971, and its successors like BSD Trek, were flying way below the radar of any lawyers back then. Even through the early/mid-80's, developers took great liberties with IP and largely got away with it. (Regard the "Prisoner" game from 1980 [1].) I remember buying a C64 port of Trek off the shelf at Target in the mid-80s which was clearly not licensed. I don't think anyone could get away with that today. :) [1] https://en.wikipedia.org/wiki/The_Prisoner_(video_game)#Differences_between_the_TV_series_and_the_game https://en.wikipedia.org/wiki/The_Prisoner_(video_game)#Diff...
