TRON
IMPORTANT
NOTE
DO NOT plug in your new game yet.
Before you do anything to your game, we
recommend that you read SECTIONS I
and II of this manual completely. It will
not take more than afew minutes and it
may be very helpful.
IIntroduction
•TRON is aone or atwo player game. There are three
models: the “UPRIGHT”, “MINI”, and “COCKTAIL
TABLE”. When the two player mode is selected on
the Upright or Mini model, the players take turns at
the controls to take TRON through the game course.
If you have purchased the Cocktail Table model of
this game, the rules of play are the same. The only
difference is that in the two player mode of the
Cocktail Table game, the picture flips to face you
when it’s your turn.
When playing this game, TRON is under YOUR
control. YOU make him move back and forth across
the screen to confront his opponents, alien and
otherwise. The methods he uses to eliminate these
opponents depend on which phase of the rack he
is in.
The game is displayed in “racks”; each of which has
four completely separate phases. By using the
control stick, the contestant(s) can determine which
of the four phases he will send TRON into. Once
TRON has entered and completed aphase of any
particular rack, that phase will not be available again
until all of the other remaining phases in that rack
have been completed. If TRON is eliminated in any
particular phase, the next TRON is allowed to re-
enter that phase to play it over again if you want
him to.
The four phases that make up each rack are as
follows:
PHASE #1—TANKS: You are provided with atop
view of amaze with yourTankand enemy Tanks in it.
The higher the number of the rack you are in, the
greater the number of enemy Tanks in there with
you. This phase ends when all the enemy Tanks are
destroyed —or —when you are.
PHASE #2 —GRID BUGS: Aside view of avertical
grid is presented to the player in this phase. The Grid
Bugs (which look something like spiders) begin to
appear and start multiplying immediately. At the
same time they are also coming after you. Shoot as
many of these as you can while working your way to
the I.O. TOWER in the center of the screen. Once
you enter this 1.0. TOWER, this phase is over.
PHASE #3 —CYCLES: In this phase you have atop
view of Cyclists. The higher the number of the rack
you are in, the greater the number of enemy Cyclists
in there with you. You cannot run into any walls,
cross your own light trail or cross the enemy
Cyclist’s trail. If you do, you will be destroyed. You
must box in the enemy Cyclists, forcing them to run
into either their own light trail, your light trail, or a
wall, destroying themselves.
PHASE #4 —MCP BLOCKS: Here there is arotating
cylinder composed of colored blocks that is con-
stantly descending on you. The higher the number
of the rack you are in, the greater the speed with
which the cylinder descends. You must either shoot
all the blocks out of the descending cylinder or clear
aspace so you can enter the cone shaped area at its
top. When you do either of these, this phase ends.
Bonus TRONS are awarded to you periodically
throughout the game as you reach or pass certain
preselected point values. Each item that can be shot
has an assigned point value as listed in Figure 1-1.
l-l

Major Features
There are several major features in your TRON
game: 1)There is acompletely new and easy to use
diagnostic package featuring: A) acomplete ROM/
RAM check with bad chip location information read
out on the monitor screen; B) the capability to check
each of the games’ different sounds INDIVIDUALLY;
C) provision for checking each control and switch
SEPARATELY; D) afull function Bookkeeping mode;
E) an entire options list that can be set from the front
console with NO NEED to crawl inside the back of
the cabinet and look for tiny switches located on P.C.
boards; F) asound system test; and G) a“PRE-SET”
category that returns ALL information in the Book-
keeping mode to zero and all operator selected
options back to factory recommended settings;
2) The game is equipped with a rechargeable battery
so that it won’t forget where it was the' night before at
closing —even if you turn it off. It will “remember”
this information for up to two weeks; 3) There are
four separate games contained in the program; and
4) As the player’s skill level increases, so does his fire
power to help him meet the increased difficulty of the
game.
Game Objective
The object of the game is to HAVE FUN while
constantly increasing your skill as you play, wiping
out as many of the enemy as possible each time to
get the highest score.

5.
Open the cabinet and inspect the inside of the
game for any signs of damage. See Figure 2-1.
Also check to make sure all plug-in connectors
on the wire harness are firmly seated.
NOTE: All connectors or plugs are keyed so they
will only go together when all pins are properly
lined up.
Replug any connectors found unplugged. DO
NOT FORCE PLUGS ONTO CONNECTORS.
DO NOT FORCE PLUGS TOGETHER. If it
won’t go on easily, assuming the keys are lined
up, it either does not belong there or is
damaged.
Make sure all printed circuit boards (P.C.B.’s)
are firmly seated in their connectors. See
Figure 2-1. These connectors are also keyed.
The P.C.B.’s will only go into them one way
without being damaged.
Note the location of the games’ serial number.
See Figure 2-1.
Check all major subassemblies to be sure they
are mounted securely. These are called out in
Figures 2-1 and 2-2.

6.
Make anote of any problems that can’t be easily
corrected.
Your game is designed to work properly on the
line voltage where you are located. Check your
line voltage with ameter to determine what its
value is. Then check the power input wires to the
main power supply transformer on your game to
be sure they are connected to taps which corre-
spond to your line voltage value.
If the power input wires to the main power supply
transformer are not connected to taps which
correspond to your local line voltage, move then,
to the proper taps.
If the line voltage in your area falls outside the
upper or lower limits of the range of inputs
covered by the main power supply transformer,
DO NOT PLUG YOUR GAME IN until you have
talked with your distributor and/or service man
and obtained asolution to this problem. Other-
wise you could damage your game.
3.
Interlock and power ON/OFF switches. See
Figure 2-1.
To help prevent the possibility of getting an
electric shock while working inside the game
cabinet, interlock switches have been installed
at each cabinet access door (this DOES NOT
include the coin door,in the Upright and Mini
models).
When any access door is opened, the interlock
switch installed there turns off all power to
the game.
Check each interlock switch for proper
operation.

After checking the line voltage in your area and
determining that the input wires to the main
power supply transformer of your game are
connected properly —or —after obtaining a
solution to your over or under voltage problem
from your distributor and/or your service man,
plug the game into your A.C. wall outlet.
The game ON/OFF switches for all models are
located as shown in Figure 2-1. Turn the game
on and allow it to warm up afew minutes.
Figure 2-2 Major Sub-Assys. (Cont. from Fig. 2-1)
Slowly open each access door to the game
(this does not include the coin door on the
Upright and Mini models).
As the door is opened approximately 1"
(2.54cm) the power to the game should go off
(the T.V. monitor, all the lights, and all sounds
will stop).
If this does not happen, check the interlock
switch by this door to see if it has broken loose
from its mounting or if it is stuck in the “ON”
position.
If the switch is found to be bad, turn the game
off, unplug it, and replace the interlock switch.
When done, plug the game back into the wall
outlet, close the access door, and turn the game
back on.
After the game has warmed up, repeat the
above interlock switch test.
When the interlock switch is working properly
and turns the power to the game off, power may
be restored to the game with the access door(s)
open. Take hold of the interlock switch plunger
and gently pull it out to its fully extended
position. THIS IS TO BE USED ONLY FOR
SERVICING THE GAME. See Figure 2-3.
Figure 2-3 Interlock Switch Operation
SELF-TEST:
Your new game will Self-Test itself to see if it has any
bad parts. The information it receives while testing
itself will be shown on the T.V monitor. Some
information can also be heard through the game’s
speaker system. See the GAME OPERATION sec-
tion for amore detailed description of this function.
When there is abad result according to the Self-Test,
call your distributor and/or service man to have the
trouble fixed unless it is something you can do
yourself (such as replace abad RAM or ROM chip).

GAME VOLUME ADJUSTMENT
CONTROL. (See Figure 2-4)
The game volume control pot is located just inside
the cabinet on the right side of the coin door frame.
There is only one pot. For adjustment, it may be
reached through the coin door on ALL models.
To make the sounds louder, turn the pot clockwise as
you face it (S~\ ).
To make the sounds less loud, turn the pot counter-
clockwise as you face it ().

OPTION SETTINGS:
To change the most common option settings, you
DO NOT have to take the game apart or go into the
cabinet and hunt for tiny switches on P.C. boards.
These most common options can be changed from
the main console of the game while it is in the Self-
Test mode. The Self-Test switch is located just inside
the cabinet on the right side of the coin door frame as
you face it.
When changing any options, ALWAYS perform the
Self-Test and play the game to be sure the ones
selected are working properly. Of course, when you
must change one of the switches that is located on
one of the game’s P.C. boards, it is also recommend-
ed that you perform the Self-Test and play the game
to be sure the switches have worked properly and
that no switches were accidentally moved that were
not meant to be. (These switches are small and this
can happen.)
The P.C. Board option switch settings, and what they
will make the game do are shown in Figure 2-6.
These switches are MAINLY INTENDED for use by a
technician who is checking and/or performing tests
on the game. See Figure 2-5 for option switch
locations.
NOTE: In order to set the option switches located
on the game’s P.C. Boards, these Boards need not
be removed from their card rack.

SELF-TEST MODE
The Self-Test mode is aspecial mode for checking
game play statistics as well as game switches and
computer functions. It is the easiest and best way to
check for proper operation of the entire game.
NOTE: Putting the game into Self-Test WILL NOT
cause the game to erase any CREDITS it has in its
memory when the Self-Test mode is entered.
You may begin aSelf-Test at any time by sliding the
Self-Test switch to the “ON” position after the power
to the game is on (the Self-Test switch is located just
inside the cabinet on the right side of the coin door
frame as you face it) .When this is done, the game will
react as follows: <
1. If the game is in the Attract mode when the Self-
Test switch is moved to the “ON” position, it will
finish the sequence and then go into the Self-Test
mode. This is illustrated by the display of the Self-
Test Mode Menue on the monitor screen.
2. If the game is in the Ready-To-Play mode or the
Play mode when the Self-Test switch is slid to the
“ON" position, it WILL NOT go into the Self-Test
mode until AFTER the players’ last TRON has
been eliminated (the game MUST be over). At this
point, the game will go into the Self-Test mode.
Again, this is illustrated by the display of the Self-
Test Mode Menue on the monitor screen.
Once you are IN one of the Self-Test mode
categories, FOLLOW THE ON-SCREEN IN-
STRUCTIONS TO COMPLETE THE TEST.
3.
The fastest way to enter the Self-Test mode is to
slide the Self-Test switch to the “ON" position and
then activate the “TILT” switch located on the
back side of the coin door just below the lock
mechanism. The game will then IMMEDIATELY
go into the Self-Test mode.
The Self-Test mode has eight (8) major categories as
illustrated by Figure 3-2.
1.It is easy to select what category you want to enter.
By pushing forward or pulling backward on the
controler stick, the Cursor at the left of the screen
can be moved UP and DOWN, (forward=UP) and
(backward=DOWN), until it is in front of the
category you want to test. Release the controler
stick at this time.
2. After the Cursor has been positioned, pull the
trigger on the controler stick and the monitor
screen will display the test category you have
selected.
NOTE: There is one exception to this. If you
position the Cursor in front of the “PRESET”
category on the Self-Test Mode Menue, when you
pull the trigger on the controler stick —EVERY-
THING, Irepeat —EVERYTHING; including ALL
information in the “BOOKKEEPING” mode, and
ALL operator selected options, will be set back to
zero “0” and to the factory recommended settings
—respectively.
3.
The next group of figures shows the CORRECT
screen presentation for EACH category of the
Self-Test mode.
During the SELF DIAGNOSTICS section of the Self-
Test mode, yd>u will first see across hatch pattern on
the screen for about 1/2 second. Second, you will
see alot of different colored bars shown on the
monitor screen. These bars will be UNpainted one at
atime from the top down. Third, you will see the
screen painted Red, Blue, and Green in bars from the
top down. Fourth, another group of colored bars is
displayed. This sequence is repeated several times.
And finally, this sequence is replaced by this mes-
sage: “HIT FIRE BUTTON TO EXIT”. If the Fire
button is not hit, the test will repeat itself. This feature
was designed into the game to enable over-night
testing for an intermittent hardware problem.
