Hi guys...

I have a power supply that is unaccounted for (I don't know what it goes to in the heap o'gear that I'm sorting through).

It's black and has a silver label on the brick:

Suntron
Power Supply
PS #100
Model No: DV-512CM
Input: 117V AC 60Hz 40W
Output: 5V DC, 8.5VA
9V AC, 9VA

Pin 5 +5V
Pin 6,7 9VAC
Pin 2 Ground

The business end of the cable is round and only has 4 pins.

I know it's not to the Excelerator+ drive because it doesn't fit any of the ports in the back. I also know it's not for the 1581: that ps port's pins are symmetrical and this ps' pins are not (in fact, these pins look "all over the place").

Any help would be appreciated.

Thanks!

Bob

It kind of sounds like a 3rd party C64 power supply. 5V 1.7A = 8.5VA, 9V 1A = 9VA. Does the connector match the C64 one identically?

Oh, jeeze. You're absolutely right...the pins are identical to a normal C64 PS. What I can't figure out though...with all of these normal C64 PS (there are 4 of them), why would anyone change a C128 PS (square plug), to a C64 one (round plug)? :confused:

I'm confused. The Suntron shipped with the round connector, right ?

It did, yes.

Sorry, I had switched topics to one of the other bricks I have here. It was originally for the 128, but it was converted to 64 instead. Was just wondering why when there's several normal 64 bricks that would have done just fine.

Maybe they figured the 128 supply to be more reliable for their 64?

Does it look any easier to take apart, or is it fused, or anything special like that ?

It looks much easier to modify than the C64 brick. It's only screwed together where the C64 brick looks fused together.

There's your answer, then. Someone probably got tired of the C64 PSU blowing.

I use a modified C128 power supply exclusively on my C64. It's vastly more reliable than the C64 power supplies, and it supplies more "juice" for powering things like RAM Expansion Units and other "goodies". :)
