Apple Adjustable Keyboard, Model M1242. This unique keyboard doesn't share parts with any other model. Keyboard tested to work, although several keys have the common malady of not registering a key press and then you get a bunchhhhhh. Cosmetically Nice, it was missing the rests and flip down feet when it came in. Key caps are available on this page. Available here are the base plate, base plate screws (set of 6), side wing screws (set of 2, on set per side), flip down feet tension clips, and the top covers.
As soon as I figure out how to get the ribbon cable out of each side (see last 2 pics) more parts will be available. Please Contact me if you know how these ribbon cable clips work.
