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 your 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.

STOP

IMPORTANT

STOP

IMPORTANT

Indicates that mishandling the product by disregarding this
display can cause the product's intrinsic performance not to be
obtained, resulting in malfunctioning.

When using the cabinet that shares the coin chute between 1P and
2P (such as the NAOMI CABINET, BLAST CITY, etc.), change
the setting of the COIN CHUTE TYPE item in the COIN
ASSIGNMENTS screen, from INDIVIDUAL to COMMON.
Using these cabinets with the setting of INDIVIDUAL disables to
play from the 2P side.
For more information about the COIN ASSIGNMENTS screen,
see the Naomi Service Manual.
When having connected the power for the first time, open the
SYSTEM MENU - GAME TEST MODE - INPUT TEST screen
and test the input devices; thereby make sure that they can
function normally.
This game is available only with the NAOMI GD-ROM system. It
is not available with other hardware.
This game cannot support the competitor connection kit of the
NAOMI CABINET. When connecting the wire to the control
panel, therefore, connect it only to a single I/O board.

1. HANDLING PRECAUTIONS

To prevent electric shock or IC Board malfunctioning, be sure to
turn off the power for the cabinet when installing or removing the
IC Board.

Extraneous matter such as dust on the IC Board can cause the IC
Board to generate heat and result in a fire due to short circuit, etc.
Ensure the IC Board surfaces are always kept clean.

Use NAOMI for the cabinets compatible with JVS. Using
NAOMI for the cabinet other than those compatible with JVS can
cause generation of heat and a fire.

STOP

IMPORTANT

Be sure to connect the IC Board and connectors completely.
Insufficient insertion can damage IC Board, etc.

For the IC Board circuit inspection, only the use of Logic Tester is
permitted.
The use of ordinary testers is not permitted as these can damage
the IC Board.

Do not subject the IC Board to static electricity when installing the
IC Board in the cabinet or when connecting wire harness
connectors to the IC Board.

When soldering buttons, etc. to the wire harnesses, be sure to
remove the wire harnesses from the IC Board so as not to subject
the IC Board to heat.

Using NAOMI without the Shield Case can cause electric wave
trouble. Be sure to use NAOMI together with the accessory Shield
Case.

The monitor frequency corresponding to NAOMI is 15kHz or
31kHz.
NAOMI can not be used for the cabinet incorporating a monitor or
projector not corresponding to 15kHz or 31kHz.

Concerning the display of JAMMA VIDEO STANDARD:
JAMMA VIDEO STANDARD adopted by NAOMI is referred to as JVS. As
against this Standard, the conventional JAMMA STANDARD which employs
56P Edge Connectors adopted by ST-V, etc. is displayed as Old JAMMA
STANDARD.

The specific Manual attached to each game sometimes displays JVS as JV
STANDARD, New JAMMA STANDARD, or JAMMA 2 STANDARD
AGAINST OLD JAMMA STANDARD as JAMMA STANDARD, JS, etc.

The contents herein described are subject to change without notice.

Handling the GD-ROM Disk

IMPORTANT

Do not contaminate the disks with your
fingerprints or dust particles. Contaminated
disks may lower audio and video quality.
When cleaning the disks, do not use volatile
chemicals (benzine, thinner, etc.), cleaning
sprays, and antistatic agents.
Do not use cracked, warped, or damaged
disks.
Do not attach papers or seals onto the disks;

Use clean cloth to wipe
the disk gently and into a
radial direction.

do not scratch the disks.
Do not use the disks with a sign of peeled seals, tapes, etc.
Observing these instructions, do not insert such a non-usable disk
into the GD-ROM drive. Otherwise the inserted disk can not be
ejected.
When cleaning a heavily contaminated disk, use clean cloth that
has been soaked in water and squeezed. Then remove moisture
with dry cloth.
When holding a disk, be careful not to contaminate it with your
fingerprints.

How to Hold a Disk

With both hands:
Put your thumbs and forefingers of both
hands on the disk's 4 circumference tips.

With one hand:
Insert your forefinger into a
central hole and at the same
time put your thumb and middle
finger on the disk's 2
circumference tips.

How to Handle the Key Chip

The key chip is a precision device. Handle it carefully because it
may be damaged by heat, shock, and static electricity.
Use the key chip with the GD-ROM disk of the corresponding
game that has been shipped together with the key chip.
