My iBook G4 800 12" logic board just crapped out on me today. I have seen several 1.2Ghz iBook logic boards on ebay for around $275. My questions is: is it possible to put a 1.2GHz logic board in to replace my G4 800? I could stand the price to get another years work out of it if it were an upgrade. It is not worth it to just put the same processor in it for me. Any advise would help.
