Definately NO continuity between pin 12 Z26 and pin 15 U5. Might be an error in schematics as the track from pin 15 u5 pin 10 Z12.
Very weird, as the schematic shows Z12-pin10 goes to Prom 2 addressing, pin21, via the E2 jumper link....
MM.
Sorry guys, tested again. Wrong pin.
Trouble counting this morning
Continuity OK pin 15 U5 to pin 12 Z26.
U5 pin 15 is high
Z26 pin 12 is high
