This is no rumor. This is fact. Amdahl sells UTS, a System 5.2 compatable
UNIX that runs on 370 hardware. It will run with or without VM.
I'm using it right now. AT&T markets UTS under the name of System V/VM.
The AT&T product runs under VM only.

IBM also sells UNIX for VM. They call it IX/370 (or something like that).

I won't go into comparisons between UTS and IX/370 since I'm obviously
not an unbiased observer. I am confident though.
