From the first of the two URLs: --begin quoted text: The IBM public domain operating systems OS/360, DOS/360, DOS/VS, MVS, VM/370, and TSS/370 run under the emulator. Newer operating systems, such as OS/390, z/OS, VSE/ESA, z/VSE, VM/ESA, and z/VM will run, but cannot legally be used except in very limited circumstances for license reasons. IBM has recently marketed the latest operating systems to run on a z/PDT for development purposes only. --end quoted text Granted that I have no idea what Mr Dashwood's intentions might be... but for The Usual Suspects (COBOL '85, command-level CICS and DB2) MVS might work just fine.

When I looked at doing this way back when, MVS 3.8 was already a Granddaddy.
