Mainframes? The 8100 was a series of small machines that grew out of
the 3790. They were no more mainframes than their competitor, the S/1.
Perhaps you are thinking of DPPX/370, which ran on the 9370.
It is debatable (although maybe we shouldn't here!) - 8100 was a DPD
product, not GSD like

I guess that I should preface this with another question. Does anybody use a z
for heavy numeric computation anymore? Or has that all gone to Intel and Power
boxes? Why is that? If it is because the z architecture is not good at
numeric computation, I have a question. The internals of the z has

Yes, there are organizations that use zEnterprise servers for heavy
numeric computation. Like decimal floating point. Cryptography is another
excellent example. And you can buy optional CryptoExpress adapters if you
want to augment the excellent capabilities found in every machine. You can
