I know that I have the board support archive somewhere (schematics in PS,
format) but I have to locate it. There's also a 68k board from James
Antonakos, Peter Stark, Theo Markettos and one from "Scotty".

I'm not able to retrieve these from my home network at this point but when I
get back home, I'll create a little 68k page on my Web site and let y'all
know about it.
