Hi... Does anyone know/remember the oldest (first) realease of VM
that would run on a Z processor? I know z/VM 5.1 required a Z.
But what from earlier releases would run on a Z? 4.4? 4.3? 4.2?
"Will run" and "Is supported" are two different things.
Anything that doesn't actually require 370 mode will, I think, run
natively.
And of course if you're willing to be creative, there's nothing
stopping you from building Hercules on z/Linux and running VM/370 or
indeed CP-67 on that. I strongly suspect that it would run faster
than the native iron it's emulating, even, on a z9 or z10.
