Is the mdu 7 boards in rack? If it is there are 2 sections,the selector (12bit counter) and the speed control (electronic regulator to excite motorand generator fields.) A1 is the output board to the genarator. A7 is output for motor field and brake voltages. Does this sound like the same system?

Yes, that's the monster. And I mean monster in the worst way.
