       @valere @danmcd I’m following Krebs, but I think that’s one of the accounts that was a little glitchy - follow, status disappears, try again, eventually “sticks.”

       @danak6jq I was studying EE at CMU from 1983-1987. The professors were deeply into NMOS and CMOS at the time; TTL and ECL were dead. I remember being skeptical at the time, and surprised that they were right in the end.

       @rwwh @danak6jq Real memory doesn't forget just because you turn off the power!I remember pulling the breaker at the rear of a W2500 just for fun, and then turning it back on. It kept going as if nothing at all had happened. The power-fail interrupt copied the first 256 words of SRAM to the last reserved 256 words of core, and the restart copied it back.
