Space Travel
From Computer History Wiki
The space simulation game Space Travel was written by Ken Thompson, first for Honeywell mainframes, and later ported to a PDP-7 with a Graphic II display. A version was also available for the IMLAC PDS-1.
Source code for the PDP-7 version of the game has been recovered, assembled, and run on a emulator with display support added. Object code for several revisions of the IMLAC version also seems to exist.
