> BEAST BUSTERS "1. GENERAL INFORMATION " A. Introduction. Thank you for selecting this fine SNK product. We are sure that it will offer you many years of profitable service. You have also — acquired the support of SNK’s Customer Service Department. We are only a telephone call away, ready to answer any questions pertaining to the operation of our products. ; de In addition to telephone support, we offer direct mailing of Ser- vice Bulletins and update information simply by returning the vie : Response Card found in the back of this manual. We alsousethig ~-card:to collect feedback from operators of our products to help. “shape our future products. I will elaborate on several‘of the fea- tures that operators have requested and that have been designed into. this game: ‘SERVICE PANEL The Service Panel contains the Coin Counter, Service Switch, and Test Switch. It is located just inside the coin door on the Right front wall.'The Coin Counter-increments once for each coin drop through any of the threé coin chutes. Pushing the Ser- vice switch will add a credit to each player without incrementing the Coin Counter. The Test switch allows technicians to freeze the game video at any time for assisting with trouble- “shooting the — game electronics. : .@ PLYWOOD CABINET CONSTRUCTION The cabinet features a plywood Base and front Coin Door mounting panels. This should ensure maximum security for the Coin,.Door and make for a durable, long lasting cabinet. We have also.added L-Brackets along the front and bottom to protect the wood edges from chip damage, and there are Rollers mounted on . the cabinet floor to. aidi in moving the game. .

The gun has been designed to withstand the rough treatment expected from players. A com- plete breakdown of the replacement parts is included in this manual and may be ordered from your local SNK authorized dealer. B. Set-up Procedures This game ships from the factory ready for operation. It has been factory configured for 2 coin operation (1 coin to continue play). In the cashbox you will find 3MM and 4MM Hex key wrenches. These are included in the event service is required on the Gun assemblies. The On/Off switch is located under the Right side gun on the lower right front of the cabinet. Refer to the Dip-Switch Options on the following page and make the required changes to suit your location preferences. Adjust the Sound Volume at this time. The Dip-Switches and Sound Volume Controls can be found on the A9003-1 PCB, mounted on the Access Drawer on the floor of the cabinet (see figure 1). ig a HO rt im rt } 1P 2P ap SOL 1p 2P 3P LEFT © VOLUME RIGHT O VOLUME C 36P EDGE CONNECTOR Cc A9003-1 PCB C.I Page 2 C.

TECHNICAL INFORMATION A. Test Mode Operation Each time the power is applied to the game, the Main CPU executes a Series of tests to ensure that all of its circuitry is opera- tional. This is referred to as the Power-Up Self Test. The CPU checks all program memory ROMs and RAMS and displays the status of each. If an error occurs, the test will stop and display a relevant error condition on the screen. To place the game into manual Test Mode, access the A9003-1 PCB, flip Switch 8 of Dipswitch 2 ON, and turn the game power on. The game will run the Power-Up Self Test, and then display the first test screen. To access the next test screen, press the Start button on the Left Gun assembly. The various tests are described below: 1. GRID TEST Displays a black screen with a white grid pattern to be used for setting overall screen size and convergence. 2. COLOR TEST Displays 4 boxes that are colored Red, Green, Blue, and White on a Black background. 3. SWITCH TEST Displays a black screen with all input switch functions listed. As each switch is activated, it’s on-screen indicator will change from a to" to a an 4. GUN POSITION This test allows you to calibrate the aim function of each gun. The screen displays three targets, carefully aim the first (Left) gun at the target indicated by the arrow and pull the Trigger. After completing the three targets, perform the same procedure for the Page S seeten. peut oma erate cen tne ERT yep a Center and Right side guns. The screen will display a message in- dicating the EEPROM (Electrically Erasable Programmable Read-Only Memory) has been updated. Perform this test when- ever a gun, monitor, or PCB has been serviced, replaced, or the guns are not aiming accurately. 4, MODE This screen displays the current Dip Switch options, and shows the status of each dip switch. 5. FONT VIDEO 1 & 2 Displays various Front Video images. 6. BACK1 VIDEO Displays a Background image from the Back1 Roms. 7. BACK2 VIDEO Displays a Background image from the Back2 Roms. 8. SOUND TEST Allows you to select a Sound Code with the Trigger Switch, and generate that sound by pressing the Grenade pushbutton. Page 6 5 1L_$_|exsevo a oe a B. Wiring Diagram.

Calibration Tommy D. Lynn SNK Corporation of America Sunnyvale, California PROBLEM We have recently received a number of Beast Buster PCBs for warranty repair that have had no hardware problems. These PCBs were simply in need of proper Gun Aim Calibration. If the Gun Aim Calibration test is performed in the Manual Test Mode, and one or more Gun As- semblies are defective, the game will freeze upon power up. This is due to improper Gun Aim data stored in the EPROM on the Main PCB. 1. Open the back of the cabinet, -unsnap the cable holder, separate - the cables and unplug all three guns. 2. Plug gun #1 (THE GUN ON THE FAR LEFT AS YOU FACE THE GAME) into the Pl connectors (Figure 1). _ [J 3. Move switch #8 of dipswitch #2 { to the “On” position. |, 4. Turn the game ON. (DO NOT : TURN: GAME OFF UNTIL YOU - REACH STEP 11). LS 5. Press the start button on gun #1 _ three times. This will bring up the ‘first calibration screen. : 6. Calibrate the first screen by | aiming first at the upper left bullet splat and pulling the trigger, then the middle bullet splat and pulling the trigger and finally the lower right bullet splat and pulling the trigger. 7. Move the gun harness connec- tors of gun #1 from the P1 connec- tors to the P2 connectors (Figure 2). CAUSE As this problem can be caused by a failure of the Gun Assembly, we should not assume that changing the main PCB will solve the problem. A perfectly good PCB will show the same symp- tom anytime the Gun Aim Calibration is per- formed with a defective gun. SOLUTION If your Beast Busters passes the power-up Self Test and then locks up, determine first whether you have a defective Gun Assembly or Main PCB using the following procedure: =. 8. Calibrate the second screen by aiming first at the upper left bullet splat and pulling the trigger, then the middle bullet splat and pulling the trigger and finally the lower right bullet splat and pulling the trigger. 9. Move the gun harness connec- tors of gun #1 from the P2 connec- tors to the P3 connectors (Figure 3). 10. Calibrate the third screen by aiming first at the upper left bullet splat and pulling the trigger, then the middle bullet splat and pulling the trigger and finally the lower right bullet splat and pulling the trigger. 11. After a slight hesitation, the message EPROM WRITE COM- PLETE should come up on the screen. 12. Turn the game OFF. 13. Move switch #8 of dipswitch #2 to the “OFF” position and turn } the game on. 14. If the GUN and PCB are good, the game should go into the At- tract Mode. 15. Repeat this procedure with Gun #2 and Gun #3. 16. If the game fails to go into the OQ we attract mode on all three guns, either all three guns have a prob- lem or the problem is on the PCB. If the game fails to go into the Attract Mode with one or two guns, the problem is most likely in that gun or guns. oe 2° OOO Pas eS AAIN PCB Corse [gorse -FIGURE | ] [e) @) ce) iP cad we OO = CEs TF ss RAIN PCB « Peewee = oe Ok AAIN PCB 6 : “ Cloveaue e- .
