Apple's line of PowerBook laptops was intended for the professional and power users. The PowerBook line includes the PowerBook 100, Duo, 500, and 5300 Series; the PowerBook 1400, 2400, 3400; the PowerBook G3, G4 Titanium, and G4 Aluminum.
Hi! Which model number and processor speed PowerBook G4 do you have? The model number should be in the middle-top of the underside of the machine. Different PowerBook G4s take different Airports cards, therefore it is necessary to know the model number. Thanks!
