Hercules additionally runs at least MVS 3.8 and VM/370 R6 just fine. Reports are that it runs more modern IBM OSes as well, although it is hard-to-impossible to get a license to legally do this, except perhaps as part of your testing and disaster recovery plan. It certainly runs 31- and 64-bit Linux quite adequately. It can also run on S/390, thus providing the ultra-poor-man's VM: run Linux native, and run multiple Herc instances under it. Since it's emulating *all* instructions, uh, the speed isn't quite what you'd expect from VM. Adam
