I guess nobody knows?

Anyway, I will try tackling it myself, carefully, when I get some time. Perhaps I can try Googling, Yahoo-ing, and Bing-ing around for some schematics and stuff (I accidentally found the Apple Macintosh II/IIx/IIfx Service Source PDF the other day, so the schematics must be out there somewhere...)

Everyone feel free to chime in!
