Stanford Time-Sharing System
Stanford Time-Sharing System was the formal name for a series of experimental time-sharing systems at Stanford, called Thor, Odin, and Zeus. They ran on a PDP-1 in Pine Hall, which was shared between Patrick Suppes at IMSSS and John McCarthy's newly started AI project.
The system had twelve Philco vector displays.
There was a very early full-sceen text editor called TVEDIT, written by Brian Tolliver.
