WARNING--DISCONNECT ELECTRICAL POWER BEFORE ATTEMPTING SERVICE
Due to an error in printed board circuit layout, there is a
problem which may cause short life with the SC146D triac in both
the 4500 and 6000 series game. The error causes the current to
drive the lamp to be supplied from the gate of the triac instead
of the normal terminals. Due to the fact that the device is
considerably oversized, in normal operation (with the 4500) the
gate would handle the current even though the device was electri-
cally mounted on the printed circuit board upside down. The
failures were caused when the bulb burns out with the filament
falling across itself shorting and drawing a much higher current.
If the device had been on the board correctly, the 120 amp surge
capability of the triac would have most often saved the device
from failing.
What to do:
The fix for the 4500 and 6000 is basically the same.
1.
2.
3.
4.
5.
6.
7.
8.
Unplug the game from the wall outlet1
Remove the power supply from the game.
Turning the power supply over, locate the small printed
circuit board under the chassis.
Remove the board from the chassis by unscrewing three
mounting screws.
The triac is held to the board with one screw and nut.
Remove screw and carefully unsolder the triac from PC
board.
Reinstall the triac in the same location but on the
opposite side of the board. You must use an insulator
(fig. 1) since the metal tab of the triac is now being
mounted on the foil side of the board. Resolder triac
and reinsert screw and nut.
Reinstall PC board into chasis with three screws being -
very careful not to pinch any wires as you are tightening
them.
Place power supply back into cabinet, attach plugs from
wire harnesses, fasten down with screws, and plug into
wall outlet.

SERVICE INFORMATION
CONCERNING THE 6000 SERIES GAME
3-26-87
To update the 6000 series game to use the shorter 5 l/2” T-10 40 watt lamps instead of the 11 112” T-8 40 watt
lamps, you will need to do the following: d.
WARNING: UNPLUG THE GAME FROM THE WALL OUTLET BEFORE SERVICING!!!
1. Move the (2) lamp sockets located on the sides down to the lower end of the shadow box. The crimp-on
cormectors will have to be removed by cutting as close as possible to the connector located inside the back of
the game Wire nuts will be used to refasten these wires. The socket will bc pointing up instead of down. The
screw for the socket should be located about one inch up from the lower edge A new hole will have to be
drilled into the back panel for the wires. This can be done from the back of the game (plan ahead to get the
holes in the right spot). The Arachnid part number on this lamp is 11-0007.
2. Aluminum reflective foil with adhesive back (commonly available from an automotive supply store) MUST
be installed between the lamp and the wood shadow box for two reasons:
A: HEAT - The tape spreads the heat and protects the wood.
B: LIGHT - It reflects the light giving twice the illumination on the target as compared to the
long bulbs without the foil.
The foil that WC arc using is 2 S/8” x 9” and is bent into an “L” (the long direction) before inserting in the
shadow box. TUG part number from Arachnid for the foil is 13-0069.
Although the short bulbs can be installed without moving the sockets down, the aluminum tape MUST bc
used due to the increased heat of the shorter bulb. Moving the sockets down helps to distribute the light more
evenly.
If there are any questions concerning this update, please call l-800-435-8319 (in Illinois l-815-654-0212).

WARNING--DISCONNECT ELECTRICAL POWER BEFORE ATTEBPTING SERVICE
A problem has arisen concerning the location rhere the target inter-
face board ribbon cable connects into the sain P.C.board on the 6000
and Super 6 Plus games. Apparently, the trace that runs the control-
ling voltage for the target lasps is located directly beneath the
area where this ribbon cable Is plugged in.
There is a thin coating of
insulating film covering this trace, but after a period of tiae this
coating can rear off, leaving the copper trace exposed. Due to the
construction of the Target Interface ribbon cable, vhen the coating is
no longer present, the rav edges of the ribbon say make contact vith
this copper trace, vhich can cause target lamp flicke'ring, sinulate a
stuck segment, or simulate a throvn dart. A stuck segment simulation
locks up the gaee if the ribbon sakes constant contact, but sany tises
the ribbon vi11 short momentarily vhen a vibration occurs to the P.C.
board, such as vhen throving a dart or touching the Select or Player
Change buttons. This type of short say result In the game shoving an
extra dart throvn In a round, or the gase nay reset during play.
What to do:
1. Turn off gane, and unplug fros wall outlet!
2. Disconnect the ribbon cable casing from the
T.I.board to the main P.C.board.(see fig.11
3. Locate the trace that runs belov the ribbon
connector.(see fig.11
4. Using a piece of electrical tape, cover the
trace completely at the connector location,
and fold tape down over the P.C. board edge
(to keep connector from catching on tape).
5. Re-insert the ribbon cable into the header
on the main P.C.board.
6. Plug game into the vail, and turn it on.
7. When servicing the game in the future,
periodically check the placement of the
tape, to be sure it has not shifted.

5.4 TARGET INTERFACE BOARD
The new switch matrix design requires a new target interface
PC. board. The target interface board reads the 19 conductors
from the switch matrix and transfers it to the main board. For
troubleshooting purposes it is important to know which pins on
the target interface board will give a particular score. Thii
information is listed in Table 1 and shown in Figure 12. Wit$
the game in Test mode (at the end of test when dartkad 1s *
sensitive) or in game mode, pairs of pins can be shorted and
opened with a jumper to simulate a dart hit (see Figure 11).
This procedure cm help determine whether a scoring problem
is in the switch matrix or the game electronics.
NOTE: m SCORE WILL NOT REGISTER UNTIL
THE JUMPER WIRE IS REMOVED FROM ONE OF
THE PINS.
lf a game has a stuck segment, it can be opened electrically by
disconnecting the 19 pin ribbon. The stuck segment’s score
will then register, and the darthead can be checked for the cause
of the problem. Another method of opening the switch is to
disconnect the ribbon cable from the Main P.C.board.

procedure for the other lamp assemblies.
(See Figure 13) Drill (3) l/4" holes as close to the sides as possible and in the approximate location
of the lamp sockets. Run the black and white wire from the socket through the black tube then
through the l/4” drilled holes to the back of the cabinet.
The enclosed wire splices are used by placing stripped wires in and crushing with channel lock
pliers.
The lamp harness has three stripped wires held together with a wire tie. Using a splice, attach
the black wires to the black wire from the right lamp socket. Do the same for the white wires.
The remaining wires are for the other lamps. Match white wires with white and black with black
Screw in light bulbs and put shield on. The lamp harness can then be plugged into matching con-
nector on main harness.

STEP #5: WEB & DART ASSEMBLY
NOTE: DO NOT attach threaded rod before web is put in place.
Put the web in place and add the threaded rod from behind. Thread nut onto threaded rod to hold
web in place.

The Dart Head must be rotated 90 degrees. This will make the 11 become the 20. (See Figure 14)
The 20 has red single segments, so to conform with the standard segment colors, take the Dart
Head apart and rotate the segments one position. Do not rotate the switch matrix.
(Figure 15) Reassemble Dart Head and mount in game with the pigtails facing down. Using piece
cut out of upper cabinet in figure 2 and supplied “L” brackets mount support behind plastic front
panel, Plug pigtails into the Target Interface Board, install standoffs, and position board in the
area shown. Be careful to find a position that puts minimum strain on the pigtails. Peel backing
off the standoffs and attach below the Dart Head. (Figure 15) Optional speaker location may be
used on 5000’s without modification, on the 4500’s drill ten 5/16 dia. holes within a 3” dia. circle to
allow sound to come forward.
(Figure 16) The notch in the back door must be on the left side, looking from the rear of the game.
To accomplish this, the back door must be reversed. Cut the l/4” brace off flush with the bottom.
Add the new brace to the opposite side. The lock and speaker must also be..moved to the other side
of the door. The newer 4500 series will not have the speaker on the door; leave it where it is. At-
tach FCC label where shown in Figure 16. Connect the lamps, Target Interface Board, and
speaker to main harness and P.C. Board; close the cabinet back.

INSTALLATION INSTRUCTIONS FOR
DOUBLE BULLSEYE
- ALL GAMES
Your Double Bullseye Accessory Kit should contain the following items:
1. Inner Bull (Black)
2. Outer Bull (Red)
3. Decal
(4. New Switch Matrix (Matrix is already installed on new double bull games)
Carefully remove the dart head from your dart game by removing the 4 bolts holding the dart
head in the game. Lay the dart head flat on a table, with the white backboard facing you.
HINT: Before removin
the heads of the screws 7the eight nuts holding the dart head together, place a piece of tape on segment side of dart head) to hold them in place after nuts are removed.
Refer to your game parts manual for illustrations on how this disassembly process is done.
Disassemble and reassemble dart head as follows:
a) Remove the 8 nuts holding the target back to the spider.
b) Remove the switch matrix.
c) Remove white molded matrix cushion (older dart heads use a clear vinyl gasket and a red rub-
ber damper)
d) Check for dirt and broken tips between spider and cups. Install new double bullseye.
e) Clean and reinstall matrix cushion. The smooth side of the cushion comes in contact with the
segments.
IMPORTANT
THERE SHOULD BE A SMALL U SHAPE CUTOUT ON THIS CUSHION. POSITION IT TO
THE LEFT OF THE CENTER LOCATION HOLE AT THE “20” SEGMENT ON THE SPIDER
(BEHIND THE “DOUBLE 1” SEGMENT).
0 Ifyour kit includes a new Switch Matrix, install it with the tails on the left and the 9 pin con-
nector on top. Store the old Matrix in a safe place. Ifyourkit does not contain a new Matrix, simp-
ly reinstall the old one in the same manner.
g) Clean and reinstall target back and 8 nuts, tighten only finger tight.
NOTE
BOLTS MUST BE FINGER TIGHT ONLY. ANY TIGHTER COULD CLOSE CONTACTS IN
THE MATRIX AND CAUSE INACCURATE SCORINGORNO SCORING AT ALL.

ALTHOUGH THE DART HEAD IS DISASSEMBLED AND REASSEMBLED AS IN THE PAST
(WITH 4500 AND 5000 SERIES GAMES), WITH NEWER 4850’S, 6000’S AND 7000’S IT IS
INSTALLED WITH THE 3 LEADS INTHE DOWNWARD DIRECTION. THIS MEANS THAT
THE “20” ON THE YELLOW SPIDER IS NOT AT THE TOP. THE PROGRAM WAS
MODIFIED TO REFLECT THIS CHANGE. MAKE SURE THAT IF USING A DART HEAD
FROM AN OLDER SERIES GAME THAT THE RED AND BLACK SEGMENTS ARE IN
THEIR PROPER ORDER (SINGLE 20 IS RED).
ACTIVATING THE DOUBLE BULL OPTION
(Important--Skip Step A if modifying a 4800 series game. Go on to Step B.)
A. FOR 6000’s AND 7000’s
On 6000 and 7000 series games, there is a 4 position Dip Switch on the main P.C. Board. Some
older 6000 games may not have this switch installed. It should be located just above U20 on
your 6000 main P.C. Board (Above U18 on 7000 P.C. boards). Install one if it is not there al-
ready. Flipping SW3 of this Dip Switch (see Figure 1) will activate or deactivate the Double
Bull. SW3 ON =Double Bull ON; SW3 OFF = Double Bull OFF (Single 50 point Bull is on).

Take the main board out of the game.
Remove resistor network US and diode network U6.
Most boards
do not have sockets for these chips so they must be unsoldered,
Using a small side cutting pliers, cut all the legs of each chip and
remove the body, Each individual pin can then be unsoldered and
removed,
Install the new 3.3K resistor network chip U6,
Remove the original EPROM from lJ15 and install the new V3,O
EPROM at lJ15.
Reinstall the main board in the game and check for proper
operation and scoring,

Concerning all Series 6000 and 7000 English Mark Dart Games
January 18, 1990
WARNING---DISCONNECT ELECTRICAL POWER BEFORE ATTEMPTING
SERVICE
We are recommending that the main fuse FS3 be upgraded from a 1.5 Amp
Slow Blow to a 2.0 Amp Slow Blow. Due to slight variances in components,
some games draw more current than others. When these games are
connected to high line voltage, the current draw gets even higher, close to the
rating of the 1.5 Amp fuse. After a period of time, the fuse will blow, even
though the rating may not have been exceeded.
Since all of the components in the power supply are rated at a minimum of 2
Amps, no damage will occur as a result of this change. Do not exceed the 2.0
Amp rating, however. If the 2.0 Amp fuse blows, there is a definite problem
in the power supply, indicating it needs to be serviced by a qualified
technician.
If there are any problems regarding this or any other service problem, please
call ARACHNID, INC. at 800-435-83 19 or in Illinois at 8 15-654-02 12.
