And wouldn't a "dial-up" facility be nice, too? We would never have had
to leave our MP3000!

And if they do, then they can test on back-level hardware natively.
What would really be nice, what would solve the "problem" for ISVs, is not necessarily full LGR
capability, but simply a "dial down" capability in VM: "I know this is really a z14, but make
it appear to this particular guest as a z12" -- which if I am understanding correctly is more or less a
subset of LGR.

Subject: Re: Determing the Presence of an Instruction
So it appears the LGR facility to limit the instruction set is not
practical for those ISVs who wish to test thei software on prior
generations of z hardware, since they probably don't have the hardware
farm (unless LGR works on a couple of zPDTs hooked together).
