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.

Adele Goldberg was at IMSSS for some time before joining Xerox PARC.

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.
