Line 69: ==Operating systems== ~~The~~When announced, the 370/155 supported both [[DOS/360 and successors\|DOS/360]] and [[OS/360 and successors\|OS/360]].<ref name=IBMarc.155 /> Being members of the System/370 family, the Model 155 and Model 165 were compatible with each other. Lacking virtual memory support, neither machine, as announced, could run a virtual memory operating system. The 370/155-II, with support for virtual memory, supported [[DOS/VS]] (DOS/360 with virtual storage), [[OS/VS1]] ([[OS/360 and successors#OS/MFT\|OS/360 MFT]] with virtual storage), OS/VS2 Release 1 ([[OS/360 and successors#OS/MVT\|OS/360 MVT]] with virtual storage), termed [[OS/VS2 (SVS)\|SVS]] (Single Virtual Storage), and Release 2, termed [[MVS]] (Multiple Virtual Storage) and planned to be available 20 months later (at the end of March 1974), and [[VM (operating system)\|VM/370]]. ==See also==
