So, I got an old PowerBook 5300 from my sister-in-law, and being an enthusiast of vintage apple computing, (although I'm not sure this is quite vintage) I'd like to bring it to working order. It boots, and everything, but it's got a lot of junk on it, and I'd like to re-install MacOS It had 7, but I'd like it to do 8. Can that be done? I'm really new to apple stuff (other than the apple II) so, where do I start? Buy OS8 Floppies? Do I need a key, like Micro$oft Windows?
