SPACEWAR

   A  space-combat  simulation  game,  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. This
   game was first implemented on the PDP-1 at MIT in 1962. In 1968-69, 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 commercialized as one
   of  the  first  video games; descendants are still {feep}ing in video
   arcades everywhere.
