I have an upright Missile Command that I am trying to get working and the power brick looks like it has seen better days. Before I go through and clean it all up and start having pieces powder coated I would like to check all of the voltages to make sure they are in the ballpark.

Anyone know the voltages and corresponding voltages? If you have the same for the AR I would appreciate that as well. That bad boy is next on my list.
 
All of the voltages are accessible from test lugs on the AR-II. If they all check out, chances are good that the power brick is fine. Here's the AR-II pinout for rev-02 and rev-03. They're the same except the rev-03 has a higher current limit on the -5V and +12V.

-03
J6-1 GND
J6-2 GND
J6-3 +10.3VDC
J6-4 GND
J6-5 +10.3VDC
J6-6 +10.3VDC
J7-1 GND
J7-2 -SENSE
J7-3 +SENSE
J7-4 GND
J7-5 +5V
J7-6 +5V
J7-7
J7-8 SPKR1IN
J7-9 SPKR2IN
J8-1 GND
J8-2 GND
J8-3 SPKR2
J8-4 SPKR1
J9-1 GND
J9-2 GND
J9-4 36VAC
J9-5 36VAC
J10-1 +22VDC
J10-2 +22VDC
J10-3 -22VDC
J10-4 +12VDC
J10-5 GND
J10-6 -22VDC
J10-7
J10-8 GND
J10-9 -5VDC
J10-10
J10-11 GND
J10-12 GND
 
Here's the pinout for the AR-I rev-01. Note that the +10V outputs might or might not be present.

-01
J6-1 GND
J6-2 GND
J6-3 +10.3VDC

J7-3 +SENSE
J7-4 GND
J7-5 +5V
J7-6 +5V
J7-7 AUD DIS
J7-8 SPKR2IN
J7-9 SPRK1IN
J8-1 GND
J8-2 GND
J8-3 SPKR2
J8-4 SPKR1

If the AR2 voltages don't check out, you'll probably want to check the power supply voltages - look for the 12 pin molex on the right hand side of the power assembly.

4 columns of 3 pins. Column 1 = pins 1-3 from top to bottom, colums 2 = pins 4-6 etc.

You'll be looking for:

Pins 1&2 = 10.3VDC
Pins 4&6 = 25VAC
Pins 4&5 = 12.5VAC
Pins 11&12 = 6.3VAC
