Wizard of Wor Midway, 1981
--------------------------
There are nine boards in the Wizard of Wor boardset:
Qty Position on
Motherboard
1 *Game Bd A084-90708-A961 J6
1 *Memory Bd (ROM/RAM) A082-91397-A000 J5
1 Pattern Bd A082-91348-0000 J4
1 CPU Bd (C.P.U.) A082-91354-F000 J3
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).

It will then be quiet until touched again.)

Special Note:
When setting the switches SW#1, SW#2, and SW#3 to either of the following two
combinations, _only coin meter number 1 will count_.

If the above three switches are set to any other combination, coin acceptor
number 1 will cause coin meter number 1 to count and coin acceptor number 2
will cause coin meter number 2 to count.
