I'm new to macs, but I love camera work. So I got an iBook G4 PowerPC 1.33 GHz from my friend for like 100 bucks. It has only 256 MB Built-in RAM. So to use Final Cut Pro 5 Studio I got from my uncle I guess I need 512 MB of RAM (I learned this from an error message when I open the program). So if anyone has any idea where I could buy a chip for the amount of RAM I need for cheap??? I know my lingo stinks haha! Thanks!!
