So, I received a 12" iBook G4 from a friend. She said that they told her the motherboard/logic was going out, so she just decided to buy a new one instead of fixing it. It's model #A1054 if that helps. Don't hold it against me, but I'm a Windows user for the most part because it's what I do at work, so I don't normally work on Macs. As far as I can tell this is the 1.0Ghz board. I am curious if I can remove this one and get the 1.2Ghz without any problems. I know that may sound like a stupid question, but like I said, I really don't know. I figure for a free laptop, it's definitely worth putting a little bit into to fix it up. Also, where could I look, other than eBay to find a board for it? Thanks in advance for any help!
