6. Solder the other end of this jumper wire to pin 23 of the IC socket at location 3K (see Figure 3).

7. Cut another 1 1/2-inch piece of jumper wire off the wire strand, and solder it to pin 26 of 1J/K.

8. Solder the other end of this wire to pin 26 of 1H.

9. On the component side of the PCB, use an integrated-circuit puller to remove the ICs at locations 1H and 1J/K. Save these ICs for possible use in another STAR WARS game.

Be sure to orient the index of the replacement IC in the same way the original IC was oriented. Take care not to damage the IC pins during installation into the socket.

H. INBTRLL THE PCB SET IS THE CABINET

Perform the following procedure to install THE EMPIRE STRIKES BACK PCBs in the EMI cage.

I. Slide the PCB assembly into the EMI cage.

2. Push the nylon snap-in fasteners on the EMI Shield PCB to the locked position (in).

3. Plug in the harness connectors to the edge connectors on the EMI Shield PCB.

4. Replace any screws or tie wraps that secure the harness connectors to the EMI Shield PCB edge connectors.

5. Close and lock the rear access panel.

5. Check that the Memory Expansion PCB was properly installed.

6. Check that all PCBs are properly inserted into the Interconnect PCB and the EMI Shield PCB.

7. Check the connections of the main harness to the PCB set.

No Audio

1. Check that the ICs installed on the Sound PCB were properly installed in the correct location and oriented properly.

2. Check that the Sound PCB trace cuts for this conversion cure truly open.

3. Check that no solder bridges or splashes occurred during the conversion of the Sound PCB.

4. Check the Audio Harness for the correct orientation and for proper connect ion on the Sound PCB and on the Main PCB.

Audio is OK But No Video

1. With an oscilloscope, check the X and Y video output signals fran the Analog Vector-Generator PCB. (Refer to the STAR WARS manual).

2. With an oscilloscope, check that the X and Y video signals are present at the display. (Refer to the Color X-Y Display manual.)

K. HSDBB DISPIAY IS MODIFIED OOWC1LY

Hie following modifications must be made to the game display. These modifications were previously distributed by Atari in the form of a Tech Tip; however, the complete procedures for modifying the display are repeated in Table 6 for your convenience. Ensure that all the modifications listed in Table 6 have been made to your display.

1. Connect two type-lN754A zener diodes (part no. 131002-001) together by bending the anode ends of both diodes into a "fish-hook." Hook the two fish-hooked leads together and solder them. Remember that too much heat will destroy the semiconductor material.

2. Connect two type-lN756A zener diodes (part no. 32-1N756A) as described in step 1.

3. Remove diode CR2, and solder in a type-lN4002 diode (part no. 31-1N4002) in its place.

4. Remove diode CR11, and solder in a type-lN4002 diode in its place.

5. Remove resistor R12, and solder in a 12 52, 1/4 W resistor in its place.

6. Remove resistor R35, and solder in a 12 52, 1/4 W resistor in its place.

7. Find resistor Rl. Connect the yellow wire that goes to R1 to the cathode of one of the type-lN754A diodes. Connect the cathode of the other type-lN754A diode to ground.

8. Find resistor R24. Connect the orange wire that goes to R24 to the cathode of one of the type-lN756A diodes. Connect the cathode of the other type-lN756A diode to ground.

9. Find transistor Q17 (type 2N3792). Solder the cathode lead of a type-1N4002 diode to the emitter, and solder the anode to the collector of transistor Q17.

10. Find transistor Q16 (type 2N3617). Solder the cathode lead of a type-1N4002 diode to the collector, and solder the anode to the emitter of this transistor.

11. Find transistor Q7 (type 2N3792). Solder the cathode lead of a type-1N4002 diode to the emitter, and solder the anode to the collector of transistor Q7.

12. Find transistor Q6 (type 2N3716). Solder the cathode lead of a type-1N4002 diode to the collector, and solder the anode to the emitter of Q6.

13. Find the zero-ohm jumpers W1 and W2. If these jumpers have brown insulation, replace them with pieces of wire. Note that the white and tan jumpers are good and don't need to be replaced.

High-Voltage PCB Modifications

Perform the following modifications on the display High-Voltage PCB.

1. Find capacitors C3 and C4. These capacitors were originally 100 nF, 35 V capacitors.

NOTE; The glass attraction shield may be attached to the back of the decal. This decal and glass shield may be saved if in good condition.

5. Remove the backing from the attraction-shield decal included in the conversion kit.

6. Align the second set of three holes in the attraction-shield decal with the counterbored holes at the top of the attraction-shield panel. Align the edges of the decal on either side of the wood panel.

7. Starting at the top of the area, use the palm of your hand to smooth down the decal. Continue to smooth down the decal around the bends and over the new attraction-shield glass.

8. Reinstall the metal bracket back to the wood panel.

9. Use an X-ACTO™ knife to trim the edges as required.

10. Using a 1/8-inch Allen wrench, install the screws that secure the attraction shield to the cabinet.

COCKPIT GAME

Perform the following procedure to apply the attract ion-panel decal to the cockpit game cabinet.

1. Using a 1/8-inch Allen wrench, loosen the screws that secure the top metal retaining bracket.

2. Using a 1/8-inch Allen wrench, remove the screws that secure the lower metal retaining bracket, set aside for later use.

3. Carefully slide the rear attraction glass down and place it on a flat surface.

4. Peel the backing from the decal and align it along one side and the top of the glass.

NOTE: Adhere this decal to the front exterior of the glass.

5. Use an X-ACTOm knife to trim edges if required.

6. Reinstall glass and bottom metal retainer.

7. Tighten top metal retainer.

N. APPLY THE TTHjE CECALS TO THE SICE PAHBU

Remove the backing and apply one decal on each side panel.

THE EMPIRE STRIKES BACK* GAME PLAY

THE EMPIRE STRIKES BACK is a one-player game with a color X-Y video display. You command LUKE SKYWALKER'S* SNCWSPEEDER* vehicle and HAN SOLO'S* MILLENNIUM FALCON* spacecraft with Atari's flight control. Your main goal is to reach the safety of the huge asteroid. To do this, you must reach the REBEL base on HOTH* and escape to the skies.

You must survive four levels of play to reach the huge asteroid. The first level of play will engage you in a battle on the surface of HOTH*. DARTH VADER* has released thousands of PRCBOTS* in search of the REBEL hideout. Your goal, as LUKE SKYWALKER cxi a SNOWSPEEDER, is to stop the PRCBOTS from sending pictures of the REBEL'S* power generator to DAR3H VADER.

The second level of play continues with LUKE SKYWALKER on his SNCWSPEEDER engaging in a spectacular battle against two types of IMPERIAL WALKERS*. AT-ST WALKERS* are small but very mobile. AT-AT WALKERS* are huge and difficult to destroy with BLASTERS*. A limited number of tow cables can be fired at AT-AT legs by using the thumb buttons. The WALKERS are advancing toward the REBELS' power generator, so the race is on to reach the REBEL base.

The third level of play engages HAN SOLO in his MILLENNIUM FALCON against a swarm of TIE FIGHTERS*. This level features a new and exciting war in the stars. If you can survive the TIE FIGHTER attack, you will slip into the asteroid belt flurry of level four.

Level four features HAN SOLO in his MILLENNIUM FALCON amidst a turbulent asteroid field. Asteroids must be avoided to reach the safety of the huge asteroid. However, TIE FIGHTERS continue to attack. C-3PO* will alert you that you have reached the safe hiding spot of the huge asteroid. Upon reaching the Huge Asteroid, DARTH VADER will appear and express his feelings towards you for having eluded him. TOE EMPIRE increases its forces as the player again tries to defend HOTH frcm DARTH VADER and THE EMPIRE.

In all levels of play you must avoid colliding with objects and enemy shots, or your number of deflector shields will decrease. Also, in all levels of play you can earn bonus points for exploding a certain number of targets. A JEDI* letter will be awarded in addition to the bonus points. Once all the letters that spell out JEDI have been awarded, you will have attained true JEDI FORCE*, which makes you invincible against all DARK SIDE* forces for a limited amount of time.

THE EMPIRE STRIKES BACK has five possible modes of operation: Attract, Select-a-Difficulty, Play, High Score, and Self-Test.
