OS/7 was an operating system created by Sperry Univac specifically for the 90/60 and 90/70 mainframe computers, but it has since been discontinued. The initial announcement occurred in November 1971, targeting the Univac 9700 model. However, its delivery was postponed from the originally scheduled March 1973 date to almost a year later, which impacted the market launch of the 9700. The first public demonstration of OS/7 took place on the 90/60 system in October 1973, with an official release set for January 1974. By 1975, OS/7 was phased out and replaced by VS/9, which was Univac’s adaptation of RCA’s VMOS operating system.
The OS/7 system supported multi-tasking and multi-programming, incorporating a roll-in, roll-out process aimed at enhancing CPU efficiency.
