Phoenix
Centuri, 1980

There are two boards to the Phoenix boardset, the logic and the CPU board.
   OVG-15D (Logic board, 12 EPROMs)
   OVG-15U (CPU board, 8085 CPU, 8 pin DIP switch, 36 pin edge connector)

The game is powered using these supply outputs:
+5V DC  @ 11 amps
-5V DC  @ 1 amp
+12V DC @ 2 amps

None of the diagrams nor the manual mention the current requirements of the
game (that is, the amps required for each voltage output).  But my game is
powered by a Peter Chou power supply and the above currents were read directly
off the power supply.

Legend:
CP = Control Panel (12 pin Molex connector, 4 rows of 3)
CH = Coin Harness  (24 pin Amp connector, 4 rows of 6, only 8 are used)
CPU = CPU Board (36 pin edge connector)
MV = Monitor Video (6 pin Molex connector, 2 rows of 3)
PS = Power Supply

According to CPU Harness Interconnect Diagram (364-10-1000):

CPU Edge Connector:

Notes:
? I don't know whether the sync is + or -.  My game is connected to an
Electrohome G07 monitor.  Sync goes to pin 5 on the monitor's MTA
connector, and there is another short wire going from pin 5 to pin 6.
A person I was conversing with said there was a handwritten negative
sign next to the sync on his schematic, so it may be negative.

 12| Chassis     -------------------=O GND

Notes:
a) CHASSIS shares a ground with the coin door (pin 24) and the speaker.
b) all these connections are hooked up in parallel
c) in the diagram --o/  o-- is supposed to represent a switch, =O
represents one of those circular connectors that usually is connected to
true ground.

Notes:
a) there is a rectifier diode (I think) between the COUNT and +5V
b) there is something that looks like a circle with a smaller circle
inside and to the left between the 0V and -5V.  Also, the letter O
on the right side of the diagram between pins 19 and 20 is a circle.
