MVS/Open Edition (MVS/OE), aimed at the growing open systems market, added TCP/IP and Unix support in an MVS address space, allowing users to run IBM, CICS-type applications, batch applications and Unix. MVS/ESA was repackaged as OS/390 as a marketing exercise but it's basically the same thing. Version: 5.1.
