System-9 Control Locations
THE ON-OFF SWITCH is on the bottom of the cabinet
near the right-front leg as you face the game.
THE VOLUME CONTROL is accessible through the coin
door on the left cabinet-wall.
DIAGNOSTIC SWITCHES ADVANCE, AUTO-UP!
MANUAL-DOWN, and HIGH-SCORE RESET switches are

Game-Adjustment Procedure and Diagnostic
Procedures for operation.
WIWAMS USES
A SPECIAL TECHNIQUE to name plugs
and jacks. Each connector receives a number, a
letter and a number. A hyphen separates the plug or
jack-designation from the pin number.
For example 1J1-3 'refers to a connector at board 1,
specifies the jack (male or board) side of the
connector, identifies the connector as number three
on the board, and stipulates pin number three.
LI
IJI Is board
1,
jock
I
(a CPU-Board jack).
LI
3P6 Is board 3, plug 6
(a Power-Supply plug).
J-designations refer to
the male part of a
connector.
i:
P-designations refer to
the female part of a
connector.

WI,
W3 through W7, W9,
W12
1
W14
and W15 should be connected. Substitute
W2 for WI when a 6802 microprocessor is used
Instead of a 6808 microprocessor.
DISPlAY BOARDS. Use the C-8363 board and 7-digit
slave disploys-5670-09439-00. Also use C-8365 board
and 4-digit dlsplay-5670-09448-00.
POWER-SUPPLY BOARD. Use the D-8345 board
(equipped with a relay).
SPEECH BOARD.
Your C-8228 board must be
equipped with the ROMs specified in the ROM
Summary.
