I have thought about this for a long time, and wondered if it would be possible. Is it possible to give a G4 iBook 2gbs of ram? Every thing I have read says the two final Models of G4 iBooks "Powerbook 6,7" can have 1.5gbs of Maxim Memory. I have the 12inch 133ghz G4 iBook. Also can OSX 10.5.8 Leopard run on an SSD? I did read in this one post where someone said "The theoretical maximum RAM for the G4 iBook is probably 2GB."
