You may well be right; I can't quite tell for sure as there's not much 
clearance between the two, but I can see a nest of wires in there.

Well, it does have some damage to it, as does another identical board that 
I have, so it's unlikely it could ever be used again; I may get a chance to

I will take a look, just for the sake of completeness.
