Apple Key Caps

All 15" & 17" Aluminium PowerBook G4s, and most of the 12" models use the type-A keyboard too, however, some of the later 12" versions of the G4 PowerBook used a different (type-D) keyboard which is easily identified by the bright green ring around the silicone dome under the key caps.

All key caps come complete with their scissor clip.
Please select the image that matches the scissor clip on a standard key from your keyboard. Note that function and modifier keys use custom clips that cannot be used for identifying your keyboard.
