Does anyone have instructions or schematics for the power board (820-1178-A)? I'm trying to keep a PowerMac G4 case/PC mod as vanilla as I can, and really want to be able to get the power button to work as it did originally.
To use the front-panel speaker, I pulled apart a usb headset cable for the little sound card on it. Then I soldered that to a tiny USB amp for a USB speaker. Then I wired that to the speaker. So, my front-panel speaker is powered off one of the USB headers of my motherboard. The components are tucked neatly away in the speaker casing. So, now, I have normal audio through the front panel speaker just like it originally had.
I'm willing to do something similar in order to get my power button and led to function as well.
Any ideas or resources you can point me to?
(Note that the 2nd image is mirrored/reversed so that you can see how the top side of the card aligns with the bottom side of the card.)
