I have a few old PowerPC Macs and I'd like to install OSX Leopard on them. I don't have the original installation discs or hard drives. After discovering that I can't just download an installer and that I need to use a physical installation disc, I figured I would just need to pick up a Leopard installation disc off of ebay. But now I'm reading in various places that just any old Leopard installation disc won't work--there are different Leopard installation discs for different mac models... Does anyone know how I would go about finding a full OSX Leopard Installation Disc that's compatible with each of the mac products listed in the title? Maybe there's some online resource that maps the OSX Leopard Installation Disc product identifiers to compatible Mac products?
