IMSSS Computer Aided Instruction group under Patrick Suppes shared a PDP-1 in Pine Hall with John McCarty's AI project. They ran the experimental time-sharing systems Odin, Thor, and Zeus. There was also Stanford Logo (SLOGO).

The PDP-1 was upgraded to a PDP-10, and a new version of Stanford Logo was created. There were Imlac PDS-1 computers acting as graphical terminals, capable of displaying turtle graphics. Douglas Hofstadter wrote his book Gödel, Escher, Bach on such an Imlac.

The PDP-10 started out with a KA10. At some point it was replaced by a KI10 running TENEX. Eventually a second KI10 processor was added.
