Hi Matt
Worked on MPH II many times. Honestly. It's not bad, it has two different versions, pretty much the same thing, you should be able to get boards from third party company, and yes, EEPROM needs SVT. I mainly use SVT to run the unit and check error code(not many there). How old are these units?
From my limited experience, most the problems involving ice-cube relays and that upside down jack(they do leak oil), if you do pick up the job and have issues,let me know.
Merry Christmas
Iggy
