The '''CAL Time-Sharing System''' (usually given as '''CAL-TSS''') was an unsuccessful [[time-sharing]] [[operating system]] for the [[CDC 6400]], written by a team at the Campus Computer Center at the University of California, Berkeley. (It was contemporaneous with the [[Berkeley Computer Corporation]] project, but other than [[Butler Lampson]], there was no cross-over between the two.)

	Design commenced in June 1968; implementation began in December 1968, and a prototype version of the system was running in July 1969. By October 1969 the system was self-supporting. The project was cancelled in November 1971, when funding was terminated~~; some~~ of the ~~staff decamped to the new [[~~Berkeley ~~Computer Corporation]].

The project was cancelled in November 1971, when funding was terminated. One of the two 6400's bought by Berkeley remained on campus, and in use, until the second half of 1982, but it ran a Berkeley variant of the usual [[Control Data Corporation\|CDC]] OS, [[SCOPE]].
