STAR WARS NOTES
Problem: The 3-D objects get funny looking,
but everything checks out okay in self test.
Solution: The problem may be AMO-type
random-access memories (RAM) in locations
SF and SH on the Main PCB. The defective
RAMs are AM9128-15 or AM9128-10.
Do not use AMO RAM at locations SF and
SH, connect a 1800 , ±5%, ¼W resistor
from pin 2 ofintegrated circuit 9D to ground.
You will find a convenient trace on the top of
the Main PCB for connecting the resistor.
Problem: The game fails to keep credit or
scorekeeping information.
Solution: The NOVRAM at location lE
on the Main PCB may be bad. When replacing
the NOVRAM (X2212), be sure that capa-
citor C94 ( 4. 7uf) is installed in the board.
Problem: Revision B and revision C boards
may not power up on the PAT 9000 tester.
Solution: In the Clock circuit on the Main
PCB, change R3 from a 220 fl resistor to a
68.{). resistor. Also change C3 from a
39pF capacitor to a lOOpF capacitor. In
addition, you must have the 0.1 fl resistor
modification done to the PAT 9000.
Problem: The option switches on the board
are set, but the game still doesn't have the
correct options.
Solution: The option switches on the board
are used only as a backup in case the
NOVRAM fails. The NOVRAM holds the
option information normally used by the
game. Use the self-test mode to set the
option information into the NOVRAM.
Problem: Games with revision A and revi-
sion B Main PCB fail to work when powered
up.
Solution: Change R3 in the Clock circuit of
the Main PCB to a 68{1 resistor.
Problem: I hear a series of beeps when
performing the self test. Which RAM and
ROM do these beeps refer to?
Solution: The self test gives off a continuous
series of 16 beeps. If the beeps are high in
tone, then the IC being checked is good; if
the beeps are low in tone, then the IC is bad.

Problem: Possible cathode-ray tube damage
while the game is in the freeze mode.
Solution: Switch 8 of the option switch at
location lOE/F puts the game into a freeze
mode. The game can be advanced through
game play, frame by frame, by pressing the
left trigger button. Care should be taken
when operating the game in this manner to
avoid leaving the screen on a frame using
high intensity levels, such as when the Death
Star explodes. If you leave the game screen
in freeze mode with a high intensity frame
displayed, you may burn the phosphor of the
cathode-ray tube.
Problem: While in the self-test mode, a
series ofletters and numbers appears on the
screen with a series of"N" and "F" letters
after it
Solution: The game has built-in diagnostics
for use in troubleshooting. Refer to the
Troubleshooting Guide included in the
schematic package for details. This guide is
available by ordering SP-225, 2nd printing.
This Troubleshooting Guide explains how
to use the diagnostics of the game when
troubleshooting.

CINEMATRONICS'
DRAGON'S LAIR TO TV HOOK UP
By Charles Howell, Take Ten Corp., Statesboro, GA
Game: Cinematronics' Dragon's Lair
Subject: Hook up of TV set to new laser disc player (LD-Vl 000)
Solution: Although Cinematronics told me that you could not attach a TV set to this
disc player without special ordering the player, it can be done by anyone willing to
spend about $30 and a little bit of time.
All that is needed is to go to Radio Shack and purchase a TV RF modulator module
(part #277-221) and the other parts listed on the instruction sheet and put it together.
This unit should be enclosed in a metal case and hooked up using shielded cable to
reduce any possible RF emissions or re~eptions.

The road to South Bend, Indiana, is paved with
quarters these days as Computer Creations
finishes work on a new laser disc video game
produced for Williams Electronics. The pioneer-
ing computer animation firm, led by President
Tom Klimek and his team of artists and
engineers, have once again created a big stir
with their eye-arresting 3-dimensional graphics
for Williams Star RiderN game, the newest
entry in the latest developmental trend in video
arcade games.
"With Star Rider, we took a completely
different approach than other laser disc game
manufacturers. We added our own high-
resolution real-time computer generated images
to the spectacular graphics and fantastic
animation developed by Computer Creations.
The graphics combined with a unique hardware
system that allows complete player involve-
ment and interactivity, make Star Rider the
most technically advanced game in the
industry," says Ron Crouse, Vice-President at
Williams Electronics.
The major differences between Star Rider
and other laser disc games are the graphics and
the playability. The cartoon images have been
replaced by videoCel animation, the exclusive
process used by Computer Creations. The
results are bold, dynamic computer graphics
which show the game player not one, but
NINE new universes. Made up of brilliantly
colored hexagons, crystals and other fabulous
forms, these worlds are inhabited by titanic
space lords, whizzing comets and cosmic flora
and fauna as yet undiscovered by men or
satellites.
As the video game player races down the
curving black strip of intergalactic roadway, he
is in control(?!) of his own speed and steers his
own course while being pursued by menacing
adversaries on spacecycles. All this action
takes place on a TV monitor screen the player
is viewing while seated on his own spacecycle
seat Speeds of up to 240 mph may be reached
by turning the controls on the handlebars - but
watch out!
Star Rider has roads that are not likely to
exist anywhere but in the Amazing Space of the
Mind that Conveived It ...
COMPUTER CREATIONS, South Bend,
Indiana, is a digital computer animation facility
dedicated to the production of excellent quality
motion graphics for use on television and laser
disc. The videoCel animation process, devel-
oped by Thomas F. Klimek, president of the
firm, is a quick and efficient way to make clean,
colorful animated graphics and special effects.
Since 1976, advertising agencies, television
stations and cable companies, corporations
and manufacturers and entertainment/program
producers have used videoCel animation for
mechanical and industrial moving illustrations,
medical explanations, television program opens,
corporate "news" magazines and special video
presentations that require elegant motion
graphics.
Artists control the process; using a data
tablet, black and white line art is the input
medium, colors are selected from a choice of
over 16 million and motion instructions are
entered into the computer via a keyboard. A
pencil test can be viewed prior to seeing the
finished key frames. Finally, the computer
electronically generates each individual frame
of video, combining the drawing files, color
files and animation instructions, and a video
processor "grabs" the segment as it is laid into
place.
Computer Creations' staff of artists,
engineers and television production profes-
sionals count on the computing power of a
DEC VAX 750 host computer, Ikonas-Adage
3000 frame buffers, triple-station Evans &
Sutherland Multi-Picture System for creation
of the vector graphic art and viewing of real-
time motion pencil tests and Ampex videotape
recording equipment for assembly of final
work.

CENTURI
GYRUSS SHORTED POWER SUPPLY PROBLEM
We recently received the following letter from Mark A. Balint, Service Manager at Coastal
Vending in Washington, D.C.
Dear Sirs:
This letter is in reference to the Centuri Gyruss power supply "PALCO", i.e., shorting out of
the power transistor "Q-3". I feel this letter would not even be necessary if"Q-3" were heat sinked
The part does not cross from Japanese to American. After finding the problem and failing
many times to cross the part, I talked to the distributor. He informed me that the part was not
available even to him! I would have to tum in the power supply for a new one at a cost of$45.
In essence, the cost of many calls out of state, money lost from the machine being down, time
and cost of sending a man to the distributor with the power supply and the cost for a new one each
time you might need one should not be necessary when the problem is known and the part is simply
unattainable.
As the technician who has to go out in the middle of the night to repair machines, I feel it is the
manufacturers' responsibility and obligation to make sure parts are available, as with foreign cars.
If any of your readers have had this problem and have found a solution, it would be greatly
appreciated if they would share that experience.
Thank you for allowing me to bring this matter to light
]Jyou have a solution to this problem or can offer Mr. Balint any.further i,iformation regarding
this problem, you can contact him at Coastal Vending Co., 2629 30th Street #2, Washington,
DC20020.
