BBN Time-Sharing System

The BBN Time-Sharing System was an early time-sharing operating system Bolt, Beranek and Newman built for the PDP-1 computer, beginning operation in September 1962. J.C.R. Licklider, who had joined BBN as a vice president in 1957, brought back the idea of time-sharing after hearing Christopher Strachey describe it at a 1959 Paris conference, and Ed Fredkin identified the PDP-1 as well suited to the concept; the BBN team built custom hardware, including an interrupt system and magnetic drum storage, to make the system work.
