- skissane 10y agoOS/360 was not the first OS. Quite a number of operating systems came before it. Examples of earlier operating systems include SHARE Operating System (SOS), first version in 1959, for the IBM 709 mainframe; which in turn was itself was based on an earlier operating system, GM-NAA I/O, first version in 1956. A very notable pre-OS/360 operating system was MIT's CTSS operating system, the first timesharing OS, first version in 1961 for the IBM 7094. The first versions of OS/360, by contrast, notably lacked timesharing – that was initially provided by alternative IBM operating systems (TSS/360 was the official answer and CP/CMS, which later became VM/CMS, the principal unofficial one); OS/360 only gained timesharing support itself when TSO was released in 1971.
