- The game's name was "Space Travel" and it consumed so much CPU time
- on their expensive GE-645 that Thompson was asked to find another
- machine for game development.
-
- He finally found an old and unused PDP-7 with no OS. A while before,
- after the MULTICS project, he and Dennis Ritchie had developed a
- new filesystem. So he hacked that one into the PDP-7, built a little
- (single user) process management around it and came out with a
- new OS which was called UNICS by Brian Kernighan. Thompson was
- allowed to port UNICS to a PDP-11 later when the company was
- working on a text processing project. I think this was in 1971.
