MVS (the acronym, the usual form, comes from its full name, Multiple Virtual Storage) is an IBM operating system for the IBM System/370 series computers. It is popular with hobbyists as full distributions are available and it runs very well under the Hercules emulator. There is a "turnkey" distribution available.
