Re: Interesting idea

A 3090-400J would require either HPO, VM/XA, or VM/ESA.  A 400J would require VM/XA or VM/ESA unless it ran in physically partitioned mode (essentially, as a pair of 3090-200Js), since HPO did not support systems with more than 2 CPUs.

Consider that a single CPU of a 3090 ran at under 20 MIPS - my, how Moore's Law has changed things!

FWIW, VM/370 supported systems from the original 370
