Does anyone out there have a logic board for a powerbook G4? I need to get one for a G4 powerbook 17" 1.67Ghz. Working or non-working would be fine (as long as its not totally fried). I'd be willing to pay a reasonable price. Or if you don't have one any ideas on where I could go to find one? My computer is out of warrenty and there is no way I can afford a brand new board. Thanks!!
