instruction to branch to the location of the instruction. I think it might have caused a
heat problem in the core or CCROS or TROS.
Possible? Or is my 76 year old brain hallucinating?
I recall that sort of thing was an issue in the CDC 7600; it could throw
parity errors because of core heating. I believe that the problem was
in the PPUs, but it's been too many years to remember accurately.
