BTW, I think you once electrically forced nWAIT high to free the
system from the Glamo's deadly grasp, didn't you ? Could that be
a way for better debugging ?

E.g., if the same wire went to a currently unused interrupt, e.g.,
conveniently accessible EINT3, then it could also activate some
debug dump code at the time nWAIT is forced.

Just an idea ...
