Actually, I think the power companies hold the power line frequency pretty closely. That's what lets them buy power from each other… And a drifting power supply frequency would cause havoc with clocks and other syncronous motors. Back when I was a field engineer with Burroughs, a drunk took out the power & backup to a customer's data center. They tried to power the place with a trucked in diesel generator. Unfortunately, the thing couldn't hold a frequency under changing loads. All the disk drives in the place went nuts, cuz their motors were changing speds. -Jim MOS via Autopilot & Amiga
