I picked up a Apple PowerBook G3 & want to upgrade the OS. It is currently OS9, I would like to upgrade to OSX if that is possible. I have OSX 10.4 build, but I keep getting a message when I attempt to install the OS that this computer is not compatable with this version of Mac OS. I had a gander at the apple site & the PowerBook G3 is listed as upgradable to OSX as long as it has Firewire. Q1? How do I tell if this laptop is firewire ready? Q2? If its not, are there any upgrades to OS9 that I can make? Thanks for any help folks.
