Identification
Determining which model of the PowerBook you have can be a challenge. The same model numbers can have a variety of processor configurations. Even if you think you know exactly which PowerBook you have, a quick trip through the laptop identification system will help you nail down exactly which model you have.
Model History
The PowerBook line originated in 1991 and was manufactured through 2006. However, the first PowerBook G3 was released in 1998, dubbed the Wallstreet. The model was the last Mac based on Old World ROM architecture. The subsequent updates to the G3 line—Lombard and Pismo—included now-standard features such as USB ports, FireWire ports, the New World ROM architecture, a standard DVD-ROM drive, as well as the inclusion of the Airport wireless card.
The PowerBook G4 replaced the G3 series in 2001, with the first model being a titanium-skinned laptop. All laptops of the PowerBook G4 line included a PowerPC G4 processor, spanning speeds from 400 MHz to 1.67 GHz. Later iterations of the G4 PowerBook switched to aluminum enclosures instead of titanium, and introduced more commonly-used components such as the AirPort Extreme card, SuperDrive, and Bluetooth capability. The Aluminum PowerBooks came in 12", 15", and 17" sizes.
