Gregory's Serverseems to be a similar issue. when it tries to jump to outvec+1 (previously stored in the 6532's RAM) it goes to 0000 instead of the actual character output routine

 so strange. different manufacturers and exactly the same failure (~20 ohm short from pin 11 to ground). must be damage caused by something the last owner did. |
pin 11 of this inverter is shorted to ground. this is the exact same problem as the last SYM-1!
