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 for HC12emulators. 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.
