INSTALLATION INSTRUCTIONS
1)  First.  Remove all access panels from the game.  Locate the original game Logic PCB’s & Power
Supply and remove from the Cabinet by first disconnecting all harnesses from the boards.  (You need
only to splice in the Main Power (110v AC) into the 3-Pin Connector (GRN/WHT/BLK).)
2)  Remove all existing game harnesses (we suggest using New Jamma Harnesses (NOT contained in the
kit) to ensure reliability).
3)   Locate the most convenient and open area of the cabinet to mount the Sports Jam GD-Rom System
Asm.  Make sure this area is free and clear of all cable harnesses and grounds, cable clamps, etc. (See
FIG. 1, inside cover).
Vacuum out or clean bottom of cabinet of dirt & miscellaneous parts (e.g.
screws, loose coins / tokens, etc.).
Remove all exterior decals and repair any cabinet damage.  Repaint
cabinet if necessary.  Remove the Monitor Plexi or if y our game plexi has
Silk-screened artwork, you will need to strip it off.
4)   Connect the JAMMA Harnesses to the JVS-JAMMA Interface Boards.  Separate the wires from each
other (i.e. Control Panel, Video, Speaker, Power Supply).  Run the various harnesses to the part of the
cabinet they go to ensuring they are dressed properly & secured to the cabinet.  (See FIG. 4 Pg. iv).
Locate the Volume/Speaker/Coin Meter Cable and connect to your existing Diag. Switch Bracket or
use the new one included with the kit.  (See FIG. 3, Pg. iii).  Note: If you are using a VGA
Compatible Monitor you can run your VGA Cable directly to the monitor or connect it to your JVS
JAMMA Interface for RGB Conversion to your JAMMA Cables.
5)   Remove  Marquee from cabinet and cut to fit the new Sports Jam  Marquee in place.
Sports Jam uses 1 Lever (Joystick) with 2 Multi-Function Switches
(Buttons) for controls and a Start Button per player.  REPLACE old
Joysticks & Buttons with the NEW ones supplied in Kit.
6)   First remove all Joystick and Button assemblies from the Control Panel.  Remove Lexan and Control
Panel Overlay.  Proceed to clean surface of the Control Panel by  removing all adhesive and dirt.  Fill
in or plug up existing button holes to set up a blank work area for your (1 - 2) templates (See Pages
VII, COPY & CUT).
7)   Carefully tape template on the Control Panel in configuration of 2  players; using a Center Punch,
mark your hole centers.  With a 1c” Hole - Saw, proceed to drill out holes for the new Control Panel
configuration.  Once drilling is complete, clean surface once again eliminating all wood chips and
dust.
8)   Install the new Control Panel Overlay by carefully peeling off the paper backing and laying down on
the panel.  Smooth it out, starting in the center and working your way to the edges (removing all of
the trapped air pockets).  If necessary, cut the edges of the overlay  excess and fold under panel.
9)   Cut out the button and Joystick Holes.  Install Joystick and buttons from kit into the Control Panel
and tighten down.  Connect all game harness wires to switches and buttons.

INSTALLATION INSTRUCTIONS
10)  Proceed to place new decals on the sides of the cabinet.  Locate a new monitor bezel, if needed, and
replace glass, if required (due scratches).  Install Instruction Placard to the back of the Monitor Glass.
NOTE:  As a precaution, disconnect the JAMMA Harness from the I/O Boards and turn power on.  With a
Multi-Meter, measure the 5v and adjust if necessary to 5.15v DC.  Measure the +12 to ensure the wires and
voltages are in the correct position.  Turn power off.  Plug in the JAMMA Harness once again to the I/O
Boards.  The Attract Mode should appear on the screen.
Adjust the SIZE, CONTRAST, BRIGHTNESS, and COLORS on the
Monitor for optimum appearance.  Adjust VERTICAL/HORIZONTAL
Hold to get a stable picture, if required.
Enter DIAGNOSTICS and adjust the Volume Level, test all Buttons &
Joystick for proper operation & wiring.  Adjust Pricing.  Coin-Up and
test out a game to ensure proper play functions are as they should be.
