Wizard of Wor pinouts 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.
