**ITS topics**

ITS, the Incompatible Timesharing System, was written in 1967 at the MIT AI Lab.  It was first running on a PDP-6, but was moved to PDP-10 KA10 processors, in 1975 to a KL10 processor, and finally to KS10 processors.  ITS was host to a number of influential programs and technologies: Lisp, Zork, MAZE, Scheme, CLU, Macsyma, SHRDLU, Lisp machines, Logo, Emacs, MacHack VI.

The museum has a real KS10 and an KA10 emulator running ITS.
