Information about Space Travel

For travel through space, see space travel.


Space Travel was an early computer game that simulated travel in the solar system. It was the development of this game that spurred the development of the Unix operating system.[1][2][3][4]

Development history

The game was originally written in 1969 by Ken Thompson for a Multics system, then ported by him to Fortran on a GECOS system, and eventually ported by Thompson and Dennis Ritchie to a PDP-7. It was in the process of porting the game to the PDP-7's assembly language that Thompson and Ritchie wrote underlying code that eventually grew into the original UNICS/Unix operating system. Some consider Space Travel the first Unix application program.
