In September 1971, the RCA Corporation announced that it was abandoning the computer industry and Sperry acquired RCAs Computer division. RCA had marketed the Spectra 70 Series (70/15, 70/25, 70/35, 70/45, 70/46, 70/55, 70/60, 70/61) that were compatible with The IBM System/360 series and the RCA Series (RCA 2, 3, 6, 7) competing against the IBM System/370. These systems all ran RCAs real memory operating systems, DOS and TDOS. RCAs virtual memory systems, the Spectra 70/46 and 70/61 and the RCA 3 and 7, could also run their Virtual Memory Operating System, VMOS. VMOS was originally named TSOS (Time Sharing Operating System), but was renamed in order to expand the system beyond the time sharing market. TSOS was the first mainframe, demand paging, virtual memory operating system on the market. At the time, IBM was in the process of transforming OS/360 to a virtual memory system through the OS/VS1 and OS/VS2 (SVS) operating systems, on the way to the subsequent release of MVS.
