There is a specific pin-out record on file for Wizard Of Wor:

            Wizard of Wor Midway, 1981
--------------------------
 
There are nine boards in the Wizard of Wor boardset:
Qty                                                Position on

2  RAM Card                A082-91356-C000           J2 & J1
 
1  Comm. Mother Bd         A082-90006-B/C000
1  RGB Interface Board     A082-91363-A/B000
1 *Audio Amp #2            A084-90907-A961
 
With the exception of those boards marked with an asterisk (*), the rest of
the boards are used by at least two other Midway games -- Gorf and Space Zap.
All three of these games -- Space Zap, Wizard of Wor, and Gorf -- also share
the same power supply (A082-90411-A000).
 
Unfortunately, each of these games uses completely different pinouts on the
main Game board.  Also, Wizard of Wor uses a different amp board (the Audio
Amp #2 vs. the regular Audio Amp board) because it uses three speakers.  Gorf
and Space Zap can only use 2 speakers.  The power supply outputs from the
motherboard are the same for all these games, which means if you have the
power supply and the motherboard, you have all the power requirements for any
one of these games taken care of.
 
The "Position on Motherboard" column refers to the fact that these boards
plug into a common motherboard much like ISA/EISA/VESA/PCI cards plug into
PC card expansion slots.

Here is most of the information for the power supply pinouts on the game
side of the power supply (A082-90411-0000).  A question mark indicates
information I was not absolutely sure about.  This power supply uses almost
exactly the same outputs and inputs as the one in Super Pac-Man (A082-
90421-0000).
