Hi Gary,
Sounds like you have a drop of coolant around the micro. Seen it a few
times on the 195s. Very hard to find and not much - just a drop or two. I
pull the micro, EEPROM and CC socket. Maybe the crystal too while your in
it. Clean the parts and the PCB and replace the parts. Hope this helps!
