Here's a web page showing the pinout of a standard PC 20-pin power supply and all versions of G4 power supplies.
the DA uses 22 pins and one of the 2 extra pins supplies +28volts. if you decide to do a mod to a standard power supply, you'll need to find a wallwart 28v power supply, probably on ebay. i am not making any claims about how this will turn out for you! http://www.outofspec.com/frankenmac/wire.shtml On Sep 4, 7:04 pm, glen <[email protected]> wrote: > My DA sounds like its snoring -- WoooOOOOoooooo_zzzzzzzzzz.
