The Berkeley Timesharing System was a pioneering time-sharing operating system implemented between 1964 and 1967 at the University of California, Berkeley. It was designed as part of Project Genie and marketed by Scientific Data Systems for the SDS 940 computer system. It was the first commercial time-sharing which allowed general-purpose user programming, including machine language.
