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.
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; most of the staff decamped to the new Berkeley Computer Corporation. The machine remained on campus, and in use, until the second halt of 1982, but it is not known if it continued to run CAL-TSS, or instead ran the usual CDC OS.
