Hmmm, next thing we'll be seeing up for grabs is one of those big 3-phase
MG sets used on the old mainframes. Power supply regulation was tweaking a
Variac and looking at a meter. Wonder how many DC amps a CDC 6600 system
(CPU and peripherals) needed? IIRC power distribution was 400 Hz AC, so
it'd take some back-of-the-envelope pencil work.
