My keyboard broke.(I think) How does one go wireless with a 1ghz emac g4 0sx 10.3.9? What all do I need. If I were to buy my same usb keyboard, is there a model number that will only work the the emac?? (Applestore does not sell these anymore) I would love a new model keyboard (aluminum) but it is my understanding that it won't work with my operating system.
