That is one thing im not sure we have chris. We have built up some information and even some documentation resources but those are all in the form of user manuals and whatnot. Sam has a friend who used to work for Snap i believe. He would be the only person I can think of who might be able to help out. Despite all my archives i do not have any motherboard schematics. I can imagine that it was a somewhat guarded piece of information and not freely available. But i'll look around.
Edit: Like the avatar by the way. Here is the one i use on most forums.
