I use an ATX power supply for my c64c Lots of amps for 5v and 12v there. 9VAC is unfortunately provided by a brick whose 5v regulator gave up the gost, but it does have the advantage of providing 9vac standby power to turn the atx psu on: C64 provides 9vdc unregulated to a relay to /poweron for the atx psu. This fires up the atx psu, which provides power to my drives, uiec, and the c64's primary 5v supply. Power off is delayed to allow me to power cycle the c64 without flashing power to everything else on the system. -David On Tue, Sep 17, 2013 at 11:15 AM, Gerrit Heitsch <email@example.com>wrote: > On 09/17/2013 12:05 AM, Jim Brain wrote: > >> >> My thinking was that folks could readily leverage all of the cheap 5VDC >> laptop power supplies around, passing the 5V through and just creating >> this additional voltage using the circuit. >> > > Most laptop powersupplies have an output voltage somewhere between 14 and > 20V.
