Apple Prototype Keyboard

I just acquired two Apple prototype keyboards. The keyboard is very small with no frame and only 58 keys. They hvae stereo-type connectors on them, as oppose to ADB, and I have an adapter box to hook them up to a Mac Plus (and they do work, btw). According to my "AppleDesign" book, they are "Cassie" keyboards, co-designed by Mannock and Esslinger for the SnowWhite Project. Does anyone have any further information on these keyboards? And how do things like this get outside of Apple? I'm under the impression Apple doesn't exactly give this kind of stuff away. On the back the keyboards read: [logo]apple apq Development Engineering PROTOTYPE S/n# Model# 1012 (the other says "1032") Does Apple start numbering at '1' or '1000'? The keyboard, btw, is obviously a prototype. The whole thing seems quite flimsy and the keys are all angled slightly differently.
