RECEIVING AND INSTALLATION
(VIDEO GAMES)
RECEIVING INSPECTION
Your game was shipped in ready—to—play condition,, However, after removal of the
shipping carton, abrief visual examination is suggestedo
Naturally, you'll want to make note of any physical damage to the game cabinet
and its external components for freight claim purposes *Considering the quality
of the shipping carton, any damage to the exterior would indicate possible
interior damage as wello
The interior of the game should also undergo abrief examination for: loose
mounting hardware (check to be sure that the major components are still securely
mounted); disconnected or loose wires, cables or harnesses; electronic devices
loose in their sockets; etc„
At this time the game serial number should be loggedo Please remember that the
game serial number will be required if you need service from your distributor
»
ELECTRICAL REQUIREMENTS
Agood earth ground is essential for the proper operation of this game or for
that matter any electronic device. Problems with instability and erratic
operation of computer—type devices can usually be traced to an ineffective
ground system. Therefore, plug the game into aproperly wired 3prong outlet.
If a3prong to 2prong AC adaptor must be used, an alternate method of
grounding the third prong must be used,
INITIAL ADJUSTMENTS
When the game is connected to AC power, one of the game sounds may be heard.
This is normal.
The audio level (volume) can be easily adjusted. This is achieved by rotation
of the volume control located on the coin door. The audio level should compete
with other machines "on the floor” to maximize play time.
OPERATOR OPTIONS
The option switches allow you to select how many credits per coin, how many
chances to play per game &bonus scoring. If your machine DOES NOT have
multiple pricing capability, refer to page 2-2, If it DOES have multiple
pricing capability, skip 2—2 and refer to page 2—3,
CREDIT BUTTON, When you push this button you can increase credits without
affecting the counter. It's the red button on the coin door.

GENERAL INFORMATION
AND PERIODIC MAINTENANCE
Your video game contains the same basic building blocks as any
other video gameo
THE POWER SUPPLY provides all the necessary voltages for the Logic,
audio section, monitor and fluorescent light. Always unplug the
game before replacing afuse,,
THE LOGIC P.C. BOARD OR BOARDS is the "brain” of the game. It
senses when acoin is dropped in the coin meter, aid gives credit.
It then reads what is happening at the operator controls, inter-
prets and computes to make the game play according to the Joystick
Rotary Control or the buttons aplayer pushes. It tells the
monitor what to draw on the screen. It tells the audio section
when to make appropriate sound effects
.
THE AUDIO OR SOUND P.C, BOARD generates all the sound effects for
the game and powers the loudspeaker.
THE MONITOR is the picture tube. It draws pictures on the tube
screen according to the instructions it receives from the Logic
P.C.B. The Picture Tube (CRT) may be a"Vector" type in black &
white. It may also be a"Raster" type in color.
THE MAIN WIRING HARNESS carries power from the power supply to the
Logic, audio section and monitor. It connects to each section
through the Molex plugs. NEVER CONNECT OR DISCONNECT THE MOLEX
POWER PLUGS UNLESS THE GAME IS UNPLUGGED.
THE RIBBON CONNECTORS carry data to and from the Logic P.C.B.
Care must be taken to plug in correctly. Red Stripe on ribbon
cable indicates Pin 1and must be connected to Pin 1on each end.
Plugs may also be color coded with red dots.
PERIODIC MAINTENANCE -The only Periodic Maintenance required is
an occasional cleaning. The very high voltage used on the picture
tube attracts dust that gradually degrades picture quality. To
clean; unplug game and let sit for at least 5minutes to let
voltages "bleed-off "
.
To clean the face of the picture tube and associated plastic parts,
remove the control panel by loosening clamps on each side of panel
on inside of cabinet. These clamps are accessible thru coin door.
Remove the plexiglas window being careful not to scratch clear or
painted areas. Window, Gray Filter (Color Monitor), Colored Overlay
(Black &White Monitor) and Picture Tube may now be cleaned with a
mild solution of dish detergent. Dry all parts with asoft cloth
and reassemble,
NOTE; Monitor may be pivoted down for cleaning by removing two
wing nuts and carriage bolts from rear holes of Mounting Brackets.

JQYSTICSK SWITCH ADJUSTMENTS
(4 WAY)
lo Adjust each individual switch as follows:
1.1 Loosen front screw on switch bracket
»
1.2 Move cam as far as possible toward switch &
hold in this position.
1.3 Rotate switch toward cam until switch contacts
close.
1.4 Continue to rotate switch until top blade
deflects approXo 1/16" as shown below,
lo5 Lock front screw on bracketo
2. After adjusting all four switches ,move lever against
side of square and check switch action -
2,1 Switch #1 must break before switch #2 makes.
No two switches can make contact at the same
time or game action will be erratic.
MOVE SWITCH UNTIL
CONTACTS MAKE -
CONTINUE TO DEFLECT
TOP BLADE 1/16"
1/16"
CAM LOOSEN SCREW
CEIECK FOUR SWITCEIES
FOR CONTACT ADJUSTMENT
1
SWITCHES MUST
BOTH BE OPEN
WHEN GAM IS
ON CENTER OF
SIDE WALL OF
SQUARE AS SHOWN
3. IMPORTANT: TIGHTEN ALL SCREWS on switch brackets to
prevent any movement after adjusting.
