3. Speaker Configuration
1 . The Sanyo model DZW 14 color monitor used
in some TARG and MAXI EAGLE games will
cycle off and on under high line voltage
conditions. If this occurs to games in your
area, the AC input to the monitor may be
adjusted.
The isolation transformer secondary which
feeds the monitor has a 1 00-volt AC tap
provided for this purpose. The wire is insu-
lated and tied off in the cable assembly which
goes to the monitor.
Use an AC voltmeter to verify that you
replace the 1 20-volt tap with the 1 00-volt tap
at the monitor connector.
2. The vertical output transistors TR-902 and
TR-903 are breaking loose from the PC Board
on some Sanyo monitors used on -the MAXI
EAGLE game.
This can be cured by coating the leads of
these transistors with either hot glue or RTV
sealant. A small amount should also be applied
between the PC Board and bottom edge of
the heat sink.
GALAXIAN SPEED UP KIT
Installing this kit increases the speed of your rocket from left to right, but also makes
the enemy fly faster, there are more of them, and they shoot faster. Suddenly the rate
at which you're playing is twice what it used to be. The enemy is all over the place
and there are more flying in their formation. Plus, when their leader flies at you he is
shielded by twice as many red ships as before. It is a contest of real skill.
Galaxian Speed Up Kit - $130.
• Easy installation - just plug in memory chips.
• Increases collection by over 50%.
• Adjust number of missiles from I to 5.
• Creates whole new challenge in the game.
ATARI STEERING TEST MODULE
Atari, for many years, has been making a steering circuit board that is used on every
steering wheel or trak ball in all games . From time to time like everything else, they
fail. Sometimes it is a royal pain to determine which is bad - the steeringP.C.B., the
main logic or wiring harness. With all the vibration and dirt this little board goes
through, it's amazing the problems aren't severe'
That's why it is important for every operator to have one of these test modules.
The module plugs onto any Atari steering P.C.B. and by rotating the steering wheel
or trak ball a setofL.E.D. 'swill illuminate sequentially ( cascade) in the direction of
rotation or reverse by rotating in reverse.
Atari Steering Test Module - $40.
• Portable 3" x 2½" .
• Battery operated - 9 volt transistor type.
• Seven L.E .D .'s flash for direction and two L.E .D .'s determine which Photo
Darlington is working.
• Detects direction jitter!
• Determines which Photo Darlington is bad.
ASTEROID CONVERSION KIT FROM LUNAR LANDER
Convert any Atari Lunar Lander into Asteroids. The kit includes front control
panel overlay to cover Lunar Lander control panel and electronic module P.C.B.
that simply plugs onto Lunar Lander P.C.B. After completing the conversion, the
game will sound and play exactly as Asteroids does!
Asteroid from Lunar Lander Kit - $650.
• Easy installation-plugs onto original P.C.B. , minutes to hook up control panel.
• Bright color and explanatory control panel overlay.
• All game options and sound are the same as Asteroids.
• Converts a non-income producing game into a WINNER!
• Accu-Shoot feature is available with this kit.
• Kit does not include Asteroids overhead sign. Contact your local distributor.
These transistors are mounted on heat sink
LGL-B and located on the left side of the
chassis in front of the fly back transformer.
3. Some games were inadvertantly shipped with
a resistor soldered across the speaker
terminals. No Centuri game to date uses this
configuration . Those games using a speaker
with a magnet diameter of two inches or less
require a series resistor of 1 Oto 20 ohms, 5
watt.

ASTEROIDS ACCU-SHOOT KIT
Convert any Asteroids Video Game into a much faster skilled game' The little
flying saucer presently appears on the screen shooting at your ship with good
accuracy. Now make that saucer shoot with very high accuracy! Stop them from
waiting to get 1,000 points time after time. This kit prevents extremely high scores
and increases operator collections.
Asteroids Accu-Shoot Kit - 02 Version - $50.
Asteroids Accu-Shoot Kit-01 Version ( on the memory chips they are stamped
01 or 02) - $75.
• Easy installation - just remove existing memory and plug in Accu-Shoot Kit.
• Increases collection by 30%.
• Stops players from hanging on game.
• Route collector can install in minutes.
• Increases player excitement with new challenge.
SPACE INVADER CONVERSION KIT
Convert just about any Midway Video Game made from Gunfight on. The kit
includes a new game P.C.B., memory chips, control panel buttons and control panel
overlay with installation instructions.
Now, make use of equipment that was just about worthless and transform it into a
winner! You can never have too many Space Invaders at the cost of this kit! Convert
now for tomorrow's collections.
Space Invader Regular Kit - $400.
Space Invader Deluxe Kit - $430.
Space Invader Backglass for Gunfight Cabinet - $65.
SPACE INVADER CHANGE-OVER KIT
The Original Space Invader (Blue) is still a great game today but many operators
would like to change the game play to the Deluxe (Red) to boost collections. Some
operators have Deluxe and would like to go back to Regular. This kit does both! By
flipping a switch on ournew memory P.C.B., you can go back and forth. Now every
couple of weeks you can change the play to keep those collections up.
Space Invader Change-Over Kit - $150.
• Plug in memory board.
• When ordering, please specify what game you own.
All kits are guaranteed for 30 days efier date of shipment.
