And such problems aren't mentioned in my programmers' guide and operation
manuals.
IIRC, it was indeed a problem on the CDC 7600 PPU's. A very tight (e.g.,
UJN 0) loop would cause core to overheat. The 7600 added a duty-cycle
integrator so that repeated accesses to the same location in a short
amount of time would actually slow things down a bit to avoid that
problem. But the 7600 was a very fast machine for its time.
