Anyone ever successfully acquired one? I doubt they exist but I thought
I'd put it out here just in case. I have a 915GAC that lost its 12 volt
CPU core power distribution and another for parts that has another
unrelated fault.

I'd love to see some MOBO schematics, not because I would actually need to
use them; however I love reading schematics, and have always been interested
in how they squeeze all that stuff into such a small amount of real estate.
Something similar to 'Hacking The X-Box' would really be cool.

I'll eventually post the circuits for the original IBM PC AT if anyone
is interested.

Here is the original AT floppy and MFM hard disc controller board:
