In test mode - rom at OO (actually looks like two squares) error but game seems to play fine. Not sure what this one does.

And, how do you adjust the power if your voltages are low? Don't need to (I don't think I do, yet) but I am curious to know.

Thanks.

If im not mistakin you cant adjust the power supply if its a newer game---what year was it made?
 
I haven't seen a ROM OO error, the only voltage that is adjustable is the +5V, pot is on the AR-II board, the -5 & +12 are three terminal fixed regulators on the AR-II and the + & - 15 are also fixed regulators on the circuit boards.

Turn it on in test mode and let it do the beep test... that'll give you information that isn't clouded by a potentially malfunctioning vector generator.
 
There is a red led on the pcb indicating your pcb is getting +5. If it is not lit check your Audio/Reg board at R29 to see if it is chard. This resistor fails a lot and is caused by poor connectors on these old board sets. If it is burned up replace it with a beefier 1/2 watt 10ohm flameproof resistor mount it so air can get around it. If the resistor appears to be good sometimes just re-seating the connector will bring it back to life.
