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.
