I just received a
Performa 476 and was shocked at the amount of rust in the computer. I believe it literally sat underwater for some time. The motherboard looks like it can be salvaged but the power supply is completely covered in rust. So much so that I would never put power to it.
I may one day try and locate a replacement power supply for it but in the meantime, I have an extra PC ATX power supply (340W) I could possibly use for testing. It's too big to fit in the Perfoma's case but I'd like to use it to confirm the computer works. I don't have any other PSU's at the moment.
So my question is, can this ATX power supply be altered to work with this computer temporarily? I'm very handy with a soldering iron but I'm not that familiar with Performa's. I suppose I could look up the schematic online. But, I don't know how the Performa's "soft power switch" would work with the ATX PSU.
Any tips would be appreciated.
The Performa 476 doesn't have a soft power switch. I was thinking about my Mac IIvx when I typed that sentence. The Performa 476 has a rocker type PSU. Still, I'm unsure how the ATX PSU could be adapted to the Performa.
Is it as simple as just matching the cable colors? There are two black wires, and one each of blue, orange and yellow. I know there are standard colors for power supplies but Apple sometimes does things "differently". :-)
Thanks to Cody Gray for pointing out that information.
