Hello: This is a G4, 533 dual-processor that has been operating on OS X 10.03. I purchased Panther from allmac.com (which included upgrades to 10.2 and 10.3, so I think I have the right discs). Perhaps I didn't know what I was getting into, as I thought this would be just like any other install. I learned otherwise! Is there a manual on-line that can help me through this...or a PDF somewhere...or even a book that I can purchase? There is nothing on this computer that needs to be saved, so this could be a clean install. Any help would be greatly appreciated. Thanks.
