Hey, I just picked up a lightly used 1.07ghz iBook with 256mb ram. It's dog slow so I need some more ram ASAP. I'm on a bigtime budget so I'm thinking of just getting a stick of 512mb ram off of ebay or something. With that said, I have no fricken clue what kind of ram to get. That's where you guys come into play. What kind do I need? What do you recommend? Any help would be appreciated. Thanks!
