I am looking for a G4 PowerBook logic-board that would work with a 400mhz CPU. From what I can tell a 500mhz one would work too if it was the same year. (it came in 400mhz and 500mhz) This can come in the form of just the logic board. Or a whole laptop. If its the whole computer I would almost prefer damaged in some way so I can get a cheaper price as I have all the other parts. So if you have the Logic board in any working condition and willing to sell, please post.
