Got a 2.5" IDE hard drive (12.7mm in height or less) just laying around after you upgraded your PowerBook's internal hard drive? Turn it into an expansion bay hard drive!
Note: This unit is for use with the PowerBook G3 Series 1998 (Wall Street) which has a black keyboard. This is NOT for use with the PowerBook G3 1999 (Lombard/Bronze) or PowerBook G3 2000 (FireWire/Pismo), which both have a semi-translucent brown keyboard.
The stock 8 GB harrd drive that Apple shipped in some configurations is not compatible with this kit.
