A space-combat simulation game fOR the PDP-1 written in 1960-61 by Steve Russell, an employee at MIT. SPACEWAR was inspired by E. E. "Doc" Smith' s "Lensman" books, in which two spaceships duel around a central sun, shooting tORpedoes at each other and jumping through hyperspace. MIT were wondering what to do with a new vectOR video display so Steve wrote the wORld' s first video game. Steve now lives in CalifORnia and still writes software fORHC12emulatORs. SPACEWAR aficionados fORmed the cORe of the early hacker culture at MIT. Nine years later, a descendant of the game motivated Ken Thompson to build, in his spare time on a scavenged PDP-7, the operating system that became Unix. Less than nine years after that, SPACEWAR was commercialised as one of the first video games descendants are still feeping in video arcades everywhere.
