[ ] 1.  If  you’re assembling both kit 15909 and optional player panel 45494, skip to Step 19. If you’re
assembling just kit 15909, proceed with the next step.
[ ] 2.  Locate and unfold the player panel template. Temporarily stack newspapers, books, magazines,
etc., on the template. The weight will flatten the template sufficiently for use.
[ ] 3.  If necessary, remove buttons, joysticks and T-nuts from the old player panel and cabinet front.
Remove the panel covering and artwork from the previous game. Remove and save hinges or
mounting brackets.
[ ] 4.  If necessary, fill the old player panel holes with wood, putty, glue, etc. Allow adequate time for
materials to dry. Sand or file the player panel to a flat surface on both sides.

[ ] 5.  Place the player panel face down on top of the clear plastic cover. Center the player panel. Mark
the outside shape of the panel on the cover. Also mark hole locations. Remove the player panel
and set it aside. Cut and deburr holes for player panel buttons. Trim the cover to panel shape.
[ ] 6.  Lightly moisten the cabinet with soapy water. Remove the backing from the wallpaper decal.
Apply the decal to the player panel. Start at the top and work down. After you’ve positioned the
decal, smooth it outwards. Take care to squeeze out air bubbles. If you can’t remove a bubble,
pop it with a knife or pin. Then smooth the bubble down. Allow the decal adhesive to set.
[ ] 7.  Use a sharp knife to trim edges and cut holes for player panel buttons. Position control decals
next to the appropriate hole locations. Allow the decal adhesive to set.
[ ] 8.  Install the NBA hologram decal on the player panel.
[ ] 9.  Install the plastic cover over the decals and panel. Attach the cover and deburr the edges. Group
player controls by color (orange, red, blue and white). Joysticks are black. You must disassemble
controls for panel mounting.
 
[ ] 10.  Separate the switch from the orange PLAYER 1 START (left START) button. Bend the large
prong away from the switch just enough to slide the switch off the housing. Unscrew the nut from
the housing. Insert the button housing through its hole from the player panel‘s front. Screw the nut
finger-tight onto the switch housing from the panel back. Rotate the housing so that switch
terminals face the panel center. Tighten nuts firmly. Snap the switch back onto the housing.
 
[ ] 11.  Repeat the previous step with the other three start buttons.
[ ] 12.  Consult this chapter’s illustration Player Panel Buttons. Install the other buttons.
[ ] 13.  Tighten the pushbutton nuts firmly. Replace player panel components and hardware that you
removed earlier.
[ ] 14.  Measure the thickness of the player panel. If it is less than ½ inch (13 mm), use wooden spacers
to recess the joysticks below the surface. Thicker player panels don’t require wooden spacers.
 
[ ] 15.  Install a carriage bolt in each small hole near each joystick opening. If the player panel is thin,
place wood spacers over the carriage bolts. The spacers correct joystick-mounting depth.
[ ] 16.  Invert one joystick. Remove the E-ring from the shaft. Remove the handle and plastic ring (large
washer) from the joystick base. The bushings must remain in the base. The top of the joystick
base fits against the bottom of the player panel (or spacer, if used). Orient the connector toward
the START buttons. Align mounting holes. Attach the base to the player panel bottom. Slide the
plastic ring around the shaft so that the rough side is beside the knob handle. Slide the shaft
through the player panel and base. Replace the E-ring. Repeat this step for the remaining
joysticks.
[ ] 17.  Locate the I-40 Joystick Interface Board. Insert a plastic spacer into the bottom of a mounting
hole. Press the spacer to seat it fully. Repeat this procedure until all spacers attach to the board.
[ ] 18.  Place the I-40 Interface Board inside the player panel housing. See the housing drawing. Position
the I-40 Board near the housing’s right side. Assure that controls don’t hit components when you
open and close the panel. Leave space above and beside board connectors for mating
connectors. Mount the I-40 Board with a screw through each plastic spacer.
[ ] 19.  The completed player panel should now resemble the illustration below. Install the modified panel
housing onto the cabinet with the original mounting hardware. Firmly tighten fasteners.
[ ] 20.  Install the side and front player panel decals onto the player panel housing.

INSTALL ELECTRONICS TRAY COMPONENTS
CAUTION: Board set electronic components are static sensitive. Prepare an anti-static
work area. Ground yourself before removing circuit boards from their protective
shipping materials.
WARNING: Don’t connect cables to the circuit boards or power supply when the power
is on. Otherwise, you’ll damage VGM electronics and void your warranty.
CAUTION: Hard disk drives are fragile. Don’t stack or drop hard disk drives.
NOTICE: If your monitor requires positive sync, remove jumper J2 on the SIO Board.
[ ] 1.  Switch off power and disconnect the line cord from AC line voltage. Disconnect cables from the
VGM’s printed circuit boards. Remove the old printed circuit boards. If your VGM includes a disk
drive or drive mounting plates, remove them. Store these items in anti-static packaging from new
components.
[ ] 2.  You can attach the new electronics directly to a cabinet wall or to a separate panel. If the cabinet
doesn’t have a suitable surface, install a wood piece approximately 8 inches (20 cm) from the
rear door.
[ ] 3.  Unpack the Electronics Tray and place it on a flat work surface. Take note of the Banshee Video
Board, which is bolted to the Electronics Tray. The Banshee Video Board is a small, rectangular
circuit card. You’ll notice a steel header bracket at one of the Video Board’s short ends.
[ ] 4.  Unpack the three, unmounted circuit boards and position them over the Electronics Tray.
[ ] 5.  Find the CPU Board. The CPU Board is a roughly square board, and has a seven-segment LED
display. In the center of the CPU Board are two large, heat-sinked ICs. Position the CPU Board’s
15-pin connector beside the Video Board’s header bracket. Then plug the CPU Board into the
Banshee Video Board.
[ ] 6.  Find the Sound I/O Board. The Sound I/O Board is a roughly square board, with a JAMMA
connector on one side. This board also includes the VGM’s DIP-switch banks. Plug the Sound I/O
Board into the CPU Board.
[ ] 7.  Align circuit board mounting holes with standoff posts on the Electronics Tray. Mount the circuit
boards to standoffs with 8-32 Phillips pan head screws.
[ ] 8.  Find the Auxiliary Output Adapter Board. This is a small, rectangular board, with two connectors.
It doesn’t plug into any of the other boards. Notice the ribbon connector on the side of the
Auxiliary Output Adapter Board. Position this connector close to the Sound I/O Board. Screw the
Auxiliary Output Adapter Board to standoff posts on the Electronics Tray.
[ ] 9.  The factory installed the fans for you. They reside beneath the board set and hard drive. If you
mounted the boards vertically, the fans should blow upward, across the electronics. You’ll want to
check the airflow later. (For now, check fan markings that indicate airflow direction.)

TYPICAL ELECTRONICS LAYOUT
WIRE THE 
CIRCUIT BOARDS
 
NOTICE: 
You must install the Main (JAMMA) Wiring Harness supplied with this
conversion kit. This VGM’s 49-way joysticks require wires and circuits not found in
earlier VGMs. If the connectors in your cabinet don’t fit onto the CPU Board or wire
colors don’t match the JAMMA Chart, contact your authorized distributor for
assistance.
CAUTION: 
Insulate unused wires within the JAMMA cable, especially red, yellow,
orange and black power wires. Secure unused connectors away from the CPU Board
and its cover.
CAUTION: ATTACH CONNECTORS PROPERLY. 
Be sure that printed circuit board
(PCB) connectors mate properly. If connectors don’t slip on easily, don’t force them. A
reversed connector may damage your VGM and void the warranty. Connector keys
allow a connector to fit only one set of pins on a board.
[ ] 1.  Connect the shielded video cable between Video Board jack J4 and CPU Board plug P4. Your
video monitor requires either positive or negative sync. If necessary, add or remove the video
sync jumper at SIO Board jumper block J2. The default mode is positive sync (no jumper between
pins 1 and 2). For negative sync, jump pins 1 and 2. 
						

							Assembly          1-15 [ ] 2.  Locate disk drive power cable H-22900.2. (This cable has separate wires and plastic connectors
at each end). Attach the power cable to SIO connector P3 (near a large heatsink). Mate the plug
and jack. Press them firmly to seat contacts. The connector is keyed. Don’t use excessive force.
[ ] 3.  The disk drive power cable includes three plugs for the fans. Connect these plugs to the fans.
[ ] 4.  Secure hard disk drive and fan cables with three cable clamps from the kit. Attach the cable
clamps to standoffs at three corners of the SIO Board. Use the board’s mounting screws to fasten
the clamps to the standoffs: Position the first clamp near the SIO Board’s large heatsink. Position
the second clamp directly across from the first, near the Auxiliary Adapter Board. Position the
third clamp near the hard drive.
[ ] 5.  Locate the hard drive data cable, a ribbon cable. Orient the data cable connector over CPU Board
plug P5. Align the connector’s striped edge with Pin 1, near the video connector. (The stripe may
be red, blue or another color.) Mate the connector halves. Press them firmly to seat contacts.
[ ] 6.  Connect the Main Harness to the SIO Board edge (JAMMA). This cable has wires for the coin
door, control buttons, I-40 Joystick Interface Board, speakers, video monitor, power supply, and
so forth. Insulate and secure all extra wires (unused slam tilt switch, coin meter, etc.).
[ ] 7.  Search through the Main Harness for the Player 4 and Player 3 cables. Player 4 has gray wires
with stripes. Player 3 has blue wires with colored stripes. Connect Player 3’s plug to SIO Board
jack P14, and Player 4’s plug to P7.
[ ] 8.  Find the coin door power connector. (Look for the black, red and orange wire bundle.) Attach this
connector to plug P23 on the SIO Board.
[ ] 9.  Search through the Main Harness for the six-pin monitor connector. Plug this into your monitor.
[ ] 10.  Connect the Main Harness to the Aux Out Adapter Board at connector P1.
[ ] 11.  Connect the 20-pin ribbon cable to the Aux Out Adapter Board at jack P1. Connect the other end
of this ribbon cable to SIO Board at jack P15.
MOUNT THE ELECTRONICS TRAY
[ ] 1.  Set the electronics against the wood panel. Use the tray as a template to mark mounting hole
locations. (If you plan to mount the electronics vertically: Orient the Electronics Tray so that its
long edges are vertical and large heatsinks are at the top.)
 
[ ] 2.  If necessary, drill pilot holes for mounting screws. Use sheet metal screws to secure the
Electronics Tray to the cabinet. Attach the tray with only four corner screws. Don’t use excessive
force.
[ ] 3.  Remove the hard drive from its package. Locate the hard drive mounting bracket. Set the drive in
the mounting bracket. Align screw holes and install the 6-32 screws with spring washers.
[ ] 4.  Orient the drive and drive mounting bracket over threaded studs on the Electronics Tray. Align
the holes. Attach the bracket with 8-32 KEPSI
 nuts.
[ ] 5.  Temporarily hold the perforated metal cover over the electronics. Be certain that cover mounting
holes are accessible. Relocate the plate if necessary. Don’t install the metal cover yet. 
						

							Assembly          1-16 [ ] 6.  Locate the data and power connectors on the hard drive. Connect the free end of the hard drive
power cable to the disk drive. Mate the plug and jack. Press them firmly to seat contacts. Don’t
use excessive force.
[ ] 7.  Position the striped edge of the hard drive data cable by the power cable. Attach the cable to the
drive’s data connector. The data connector is keyed. Don’t use excessive force.
WIRE THE 
CABINET
Kit 15909, Without Optional Player Panel 45494…
NOTICE: This player panel uses 49-way joysticks and an I-40 Joystick Interface Board
(input-multiplexer circuit). The VGM requires additional wiring harnesses. These items
must be field installed to customize the unit for each kit.
[ ] 1.  Locate cable H-22785. This cable includes a fuse for protection of the Joystick Interface that
mounts in the player panel housing. This cable must be mounted in the player panel housing.
Remove the fuse from the fuse holder and retain it for reuse.
[ ] 2.  Open the player panel. Place the fuse holder beside the wall of the player panel housing. Attach
the fuse holder with a #6 short sheet metal screw (not supplied). Reinstall the fuse in the holder.
[ ] 3.  Connect cable H-22785 between the I-40 Joystick Interface Board and each joystick. Player 1
wire colors are mostly white, Player 2 wires are violet, Player 3 are blue, and Player four are gray.
The I-40 connectors are User 0 (Player 1), User 1 (Player 2), User 2 (Player 3), and User 3
(Player 4). This VGM doesn’t use the User 4 connector. Consult the Cabinet W iring Diagram, and
connect the cable wires to the switches. Secure wiring with a cable clamp and cable ties.
[ ] 4.  Connect the Common terminal of each button on the panel with a black wire. Join this wire with
the black wire from the cable. Connect the Normally Open terminals to each of the switch wires.
All Kits…
CAUTION: Prevent electrical fires and power supply damage! W hen attaching JAMMA
pigtails to the power supply, maintain fusing from the original VGM wiring. If a line was
fused before, then the new line must have a fuse, too.
[ ] 5.  See the Cabinet Wiring Diagram. Connect your power supply to the pigtail leads from the Main
(JAMMA) Harness. Red wires connect to +5 volts DC. Yellow wires connect to -5 volts DC.
Orange wires connect to +12 volts DC. Black wires connect to ground. If necessary, solder the
appropriate connector onto the Main Harness, or design your own adapter. Thoroughly insulate
soldered or pigtail connections.
[ ] 6.  Connect cabinet speakers to the pigtail leads from the Main Harness. Red-gray and brown-gray
wires connect to the left speaker. Red-white and brown-white wires connect to the right speaker.
To eliminate serious distortion, be sure to phase the speakers properly. With either speaker,
connect the red wire to the speaker’s positive phase terminal. On many speakers, a dot marks
this terminal. To test for positive phase, connect a 1.5-volt battery to the speaker and observe the
cone. If the cone moves inward, reverse the battery leads. When the cone moves outward, the
positive battery lead connects to the positive phase terminal. Mark this terminal with a dot. 
						

							Assembly          1-17 [ ] 7.  Locate the square, split ferrite bead. The
factory has installed one ferrite bead around
DC power conductors (solid color heavy
gauge wires with pin numbers 1-6 or A-F). A
second bead encircles player panel
conductors (striped color lighter gauge
wires). Install the remaining ferrite beads on
the video monitor cable and power supply
wires. The video cable bead should trap a
loop of cable. Place all beads as close to the
JAMMA connector as possible. Then close
and lock each bead. Assure that no wires are
pinched or caught in the latches.
 LOOP VIDEO CABLE THROUGH BEAD
[ ] 8.  Locate the central power ground point for the cabinet. (Ground wires are usually green. Some
may have a yellow stripe.) Assure that the previously installed ground wire from the controller port
still connects to the same central point. Reconnect ground wires that you loosened or removed in
previous steps (monitor, player panel, coin door, etc.).
[ ] 9.  Find the electronics cover. Install plastic grommet RM-37-11 over the aperture where cables pass
through the cover. This grommet part is a tough, plastic sleeve. It protects your fingers and your
cables from the cover’s sharp, metal edge.
[ ] 10.  Locate the sheet metal screws from the kit. If necessary, drill pilot holes for the screws. Install the
electronics cover. Insert a screw in every mounting hole. Fasten the Electronics Tray to the
cabinet. Tighten the screws firmly. Take care not to pinch wires.
[ ] 11.  Connect your coin door switches to the pigtail leads from the Main Harness. If your cabinet
doesn’t include diagnostic switches, you may add them now. (These momentary switches speed
up routine service calls.) Refer to the cabinet wiring diagram in Chapter Five. Thoroughly insulate
soldered or pigtail connections.
NOTICE: 
You can order the diagnostic switch bracket and switches as Midway part
number A-19542-1.
NOTICE: IF YOU’RE INSTALLING A BILL VALIDATOR, 
set the validator for 1 pulse
per dollar. Also adjust the pulse width setting. The validator must generate pulses with
these timing parameters: 50ms on (minimum) and 50ms off (minimum).

CHECK YOUR CABLING JOB
[ ] 1.  Carefully inspect cables between peripherals and the board set. The main wiring harness edge
connector (JAMMA) attaches to the SIO Board.
[ ] 2.  The hard drive data (ribbon) cable connects the hard drive to CPU Board jack P5. Be sure that
you’ve also connected the hard drive power connector to power cable H-22900.2. The other end
of this cable should connect to the SIO Board at P3.
