OS/390 is an IBM operating system for the System 370 and System 390 mainframe computers. It is basically a rebranded version of MVS with added Unix services. The OS/390 base includes a Communication Server that includes VTAM, the VTAM AnyNet feature, TCP/IP and TIOC. It provides SNA (3270), APPC, High Performance Routing, ATM support, sockets and RPC.

OS/390 itself was rebranded in December 2001 and extended to 64 bit processors and is currently called Z/OS.
