OS/7 is a discontinued operating system from Sperry Univac for its 90/60 and 90/70 computer systems. The system was first announced in November 1971 for Univac's 9700 system and was originally scheduled for delivery in March 1973.[1][2] However, the delivery slipped by nearly a year, which impacted the 9700 marketing effort. It was first demonstrated by Univac on the new 90/60 system in October 1973. The official release was then planned for January 1974.[2] OS/7 was abruptly discontinued in 1975 in favor of VS/9, Univac's name for RCA's VMOS operating system.[3][4]

"OS/7 is a multi-tasking, multi-programming system that utilizes a roll-in, roll-out capability to keep the CPU optimally busy."[5]
