RISC was sort of invented in two places at about the same time. One
of those places was Building 801 at IBM's T.J. Watson Research Center.
The other was under a DARPA program at UC Berkeley. Both of these
occurred around 1980 or so.

No, that was a different processor. I think that one was the RS/6000.
