Cluster Numbers

The label at the bottom of the backdoor of the machines contains information about power and: 

  Terma machine:
      Customer no 1000-00675    Cluster no 453305
  
  PAM machine:
      Customer no 1000-00648    Cluster no 408459

On both machines the cluster number is found at location 0x7e80…0x7e83 in the IOC EEPROM.

Power Supply interface

IOC schematic page 13, signal "PS0.ACPF~" is routed to J9 pin 3

J9 pin 1 which is the margin signal seems to originate from the RESHA board's pin 4, rather than IOC page 13, but our schematics show no circuitry for this.
