Really?  Wow.  I'm sure Seymour Cray, who designed, in the early-to-mid
'60's, a machine with 70-odd instructions, and most of the features associated
with "RISC," would be very surprised to hear that.

RISC, as a concept, is decades old, now.  Cray did the Cybers that way to
make them run quickly; at about the same time, IBM had a research project
going on to see if it could, indeed, run more quickly.  I'm fairly certain
Seymour did *his* because he hardwires his machines (no micro-code on *real*
computers 8-)), while IBM was just seeing how true and useful the 80-20 rule
was.  (I don't *think* either party was influenced by the other, but, since
I haven't had a chance to talk to Seymour [aka God 8-)], I can't be
certain.)

Then, of course, Universities got a hold of the whole idea, and it took off.
The rest is, as they say, history.
