Guest perplx Posted April 6, 2004 Report Share Posted April 6, 2004 In the hopes of making a quadruple midibox SID, i bought a c64 power supply off eBay. When I get it, I notice it's not a Commodore-brand power supply! It reads:MAXTRONMODEL PS-01POWER SUPPLYINPUT:117V 60Hz 40WOUTPUT: 5V DC 1.7A 9V AC 9VA(pinout diagram consistent with Thorsen's schematics)Are those specs the same as a REAL commodore psu? I havent found a c64 yet, so i can't test it... :'( Quote Link to comment Share on other sites More sharing options...
Wilba Posted April 6, 2004 Report Share Posted April 6, 2004 The output ratings are the same as mine, and the same as the specifications (see below). Double-check the voltages with a multimeter, just in case. There seems to be great variation in C64 power supplies, which makes sense since they're usually country-specific.My one is a black box with ventilation slots, huge transformer and a 7805 regulator with a massive (and I mean massive) heatsink. The schematics show that the older ones used a transistor to regulate voltage (apparently the transistor and 300k resistor can be replaced with a 7805).http://www.funet.fi/pub/cbm/schematics/computers/c64/c64extps.gif Quote Link to comment Share on other sites More sharing options...
