IBB B4PIBB STRIKES BACK* INBTSDCPIONS TO CONVERT STAR NAPS* ÛPRIŒT AND OOCKPIT GAMES

PWWJLUL'flON

This document contains the instructions necessary for changing an upright or cockpit STAR WARS game into a THE EMPIRE STRIKES BACK game. The conversion includes modifying the game printed-circuit boards, changing the flight control graphics and attraction shield, and verifying that all previously announced modifications have been performed on the display.

Save the STAR WARS Operators Manual, Schematic Package, and the Self-Test label to fully document your converted game. As you complete the game conversion, these instructions will refer to the STAR WARS manual; be sure to have it on hand. %

To prevent damage to the game, read all instructions before proceeding with any modifications.

TOOLS REQUIRED

The tools listed in Table 2 are required to perform a complete conversion.

Table 2 Tools Required

Quantity_Peser ipt ion_Purpose

1 Phillips Screwdriver Remove, disassemble, and reassemble the game PCB set

1 Wire Cutters Trim jumper wires

1 Wire Strippers Prepare jumper wires

1 15- to 27-Watt Soldering Solder jumper wires to PCB

Iron & Solder

1 X-ACTO™ Knife Cut traces on PCB; install decals

1 24-Pin or 28-Pin IC Pullers Remove ICs from PCBs

1 Flat-Head Jewelers Remove Microcode ROM

Screwdriver

1 Needle-Nose Pliers Install jumper wires

1 1/8-Inch Allen Wrench Remove attraction shield

B. DISASSBCLE TOE GAME PCB SET

Perform the following procedure to disassemble the STAR WARS game PCBs.

(Refer to Figure 5-9 of your STAR WARS manual.)

1. Unplug the Interconnect Cable fran the Sound PCB.

2. Use a screwdriver to remove the two screws securing the Sound PCB to the PCB spacers. Save this hardware for later reassembly. Pull off the Sound PCB from the Interconnect PCB and set it aside.

3. Pull the Interconnect PCB off the three remaining PCBs. (Hie Interconnect PCB is between the notches at the end of the game PCB set.)

4. Use a Phillips screwdriver to remove the two screws securing the Main PCB to the RF End Board spacer blocks. Save this hardware for later reassembly.

5. Lift the Main PCB frcm the Analog Vector-Generator PCB and set it aside.

C. MXIFY TOE ANALOG VBCTQR-GffllKKATOR PCB

Perform the following procedure to modify the Analog Vector-Generator PCB.

(Refer to Figure 5-13 of your STAR WARS manual.)

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

1. Use an integrated-circuit puller to remove the integrated circuit (IC) at location 1L. Save this IC for possible use in another STAR WARS game.

2. Locate the IC labeled "136031-011" in the conversion kit. Install this IC in the socket at location 1L of the Analog Vector-Generator PCB.

3. Set aside the Analog Vector-Generator PCB.

D. MODiry TOE MAIN PCB

Perform the following procedures to modify the Main PCB. (Refer to Figures 1 and 2 of this manual.)

1. fti the back (non-component) side of the Main PCB, locate the trace from pin 22 of the IC at location 1H/J. (See Figure 1.)

2. Use an X-ACTO™ knife to cut the trace frcm IC 1H/J, pin 22.

10. On the component side of the PCB, use an integrated-circuit puller to remove the ICs at locations 1H/J» 1J/K, 1K/L, 1M, IF, 7H, 7J, 7K, and 7L. Save these ICs for possible use in another STAR WARS game.

note

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.

11. In the conversion kit, locate each IC given in column 1 of Table 3. Then install that IC in the socket at the location given in column 2.

12. Find the Memory Expansion PCB in the conversion kit. Install this small PCB in the socket at location 1H/J as shown in Figure 2. Note how the snail PCB is oriented. Set aside the Main PCB.

13. If your STAR WARS main PCB does not have R59 installed and the game does not retain high scores or statistics, insert a 10K Q resistor in series between pin 10 of IE, and at the intersection of R100, CFG, and C94.
