Hello guys I have a iBook G4 notebook here with the following stats: CPU-Type: PowerPC G4 (3.3) CPU-Speed: 1 GHz L2-Cache (per CPU): 256 KB Memory: 640 MB Bus Speed: 133 MHz Boot-ROM-Version: 4.77f0 Okay, now here is my problem: I want to upgrade the memory to 1GB and I really don't know which RAM-stick I'd have to buy. (there are so many different types out there ...) Aaaaaand .... Is it possible to install Leopard on this old notebook without any problems? I'd need it for some work with Office and light photoshop stuff. Can someone of you guys give me advice? Thanks!
