It still might be a contact problem between the TWGS cable or 65816
and the processor socket. It's a known problem that the pins on the
TWGS cable are longer than the pins on the 65816. They go deeper
into the socket and have a tendency to spread the contacts in the
socket.So when you reinstall the 65816 you get a less than optimum
contact, sometimes it won't even work.
