I just got an iBook G4 from a friend becasue one of my friends broke it at my house when i was reinstalling osx and some programs for him. I had to buy the broken one and fix it but now I like this thing and want to upgrade the ram because this one only has 256. I read online that it takes pc2100 ram. Does mac take any special type of ram or just any ram that meets the speed requirements? Its an iBook G4 1.33ghz I'm liking this thing even with a F'd up 1/8th of the screen Thanks guys.
