Well, it appears to be failing its self-test. When you power it on, it never
prints a test page and is never seen on a LocalTalk net.

So, I hooked up a serial terminal to it and got the following at 1200 baud:

        *APPLE*00010008*APPLE*
        *APPLE*00010008*APPLE*
        *APPLE*00010008*APPLE*
        *APPLE*00010008*APPLE*
        [...]

I posted to Apple's Tech support site, Usenet, and AOL, but could never
get an answer as to what this code means.

It's definately the logic board, but I've got no idea where to start looking.
(Not to mention that the only socketd chips are the ROMs and a couple of PALs.)
