To end the self-test, set the self test switch to OFF. (The Service Switch is a round button on the upper right corner CPU board to the left of the dip switches. FWIW, It looks like the Test Switch grounds the test signal from CPU board pin J to the ground pin V) NOTE: This procedure does not test the coin door lockout coils. If the Self-Test passes, but the lockout coils do not energize when power is applied to the game, suspect the lockout coil wiring, coin door harness, game PCB harness, or transistor TR3 (for the Ireland-Built cabinet check TR3 and TR4) and related circuitry of the CPU PCB. SELF-TEST SCREEN 1 When the self-test switch is set to ON, the screen shows the self-test display. The ROMs and RAMs are tested at this time. The Self-Test screen looks like this (comments are in lower case). cocktail only punch joystick 0 0 0 * 0 0 color **** **** **** **** **** **** **** adjustment **** **** **** **** **** **** **** chart **** **** **** **** **** **** **** **** **** **** **** **** **** **** edge connector settings (see below) switch DIP 1 2 3 4 5 6 7 8 3A 3B 4A 8A settings 0 0 0 1 0 0 0 0 1 0 1 1 service S 0 C1 C2 right & left player 1 1 0 1 0 0 coin mechs start player 2 2 0 1 * 0 0 SOUND sound test start 0 2 joystick punch player one, or upright The COLORS from left to right are BLUE, GREEN, LT. BLUE, RED, VIOLET, YELLOW, and WHITE. Activate all SWITCHES on the control panel, coin mechanisms, and the service switch (located on the upper right of the CPU board to the right of the DIP switches). The test changes 0 to 1 as the switch is activated. SWITCH FAILURE is indicated by the proper 0 or 1 not changing on the screen when the switch is activated. (Kangaroo requires an eight-way JOYSTICK, which signals diagonal movements by allowing two adjecent switches to close at once.) Push the joystick(s) diagonally up and to the left. For proper game operation, both the top and left switches MUST close at the same time, and the top and left 0s should each become 1 (as shown above). Push the joystick diagonally and to the right, repeating the same procedure. Both the top and right switches should close, changing the corresponding 0s to 1s on the screen. The EDGE CONNECTOR SETTINGS represent harness connections on the CPU PCB. 1 means the pin is shorted to ground in the harness 0 means there is no connection in the harness. Screen Pin on CPU Shows Harness Connector 3A C 3B 3 4A D 8A J NOTE 8A is a zero if you enter self-test mode by pressing the service switch on the CPU PCB (while turning the machine on, as opposed to using the test switch on the utility panel.) ROM FAILURE is indicated on the screen by the words ERROR ROM- and a number (for a ROM failure on the CPU PCB), or the words ERROR ROM V- and a number (for a failure on the Video PCB). The following lists the ROM chips and their locations. Bad ROM Chip Location Screen Display CPU PCB ROM-0 * IC7 ROM-1 IC8 ROM-2 IC9 ROM-3 IC10 ROM-4 IC16 ROM-5 * IC17 ROM-8 * IC24 ROM-12 * IC28 Video PCB ROM V-0 IC76 ROM V-1 IC52 ROM V-2 IC77 ROM V-3 IC53 * Does not display on the screen if defective RAM FAILURE is indicated by a blank screen or by garbage displayed on the screen for a defective RAM at IC5 or IC6 on the CPU PCB. Make sure that ROM-0 and ROM-5 are good on the CPU PCB. In addition, inspect the dynamic RAM on the Video PCB at locations IC55-62, 66-73, 79-86 or 93-100. Troubleshoot using the game schematics and the CAT Box (using a Z80 interface) or a bus controller to locate the failing RAM. To test the SOUND, simultaneously press the Player 1 and Player 2 start switches. Game sounds are produced and incremented automatically from SOUND 1 through SOUND J. Game Sounds: SOUND 1 Game meoldy SOUND 2 Kangaroo jumping SOUND 3 Kangaroo punching SOUND 4 Kangaroo falling SOUND 5 Kangaroo dying SOUND 6 Apple falling SOUND 7 Kangaroo punching and apple or gorilla SOUND 8 Bonus Kangaroo awarded SOUND 9 Begin new level SOUND A Monkey dying SOUND B Kangaroo getting fruit SOUND C End of level SOUND D Bell ringing SOUND E Monkey column decreasing by one monkey SOUND F Gorilla taking Kangaroo's gloves SOUND G Kangaroo crouching SOUND H Apples falling from broken branch SOUND I Kangaroo climbing ladder SOUND J Kangaroo hopping SOUND FAILURE is indicated by no sound. Check the volume control levels on the utility panel and on the CPU PCB at VR2. Troubleshoot the following sound circuitry on the CPU PCB: G.I. sound chip at IC50, ROM 8 at IC24, Z80 Microprocessor at IC34, RAMs at IC32 or 33, or audio amplifier at IC61. To go to screen 2, push the 1-player start and either PUNCH switch at the same time. SELF-TEST SCREEN 2 A white crosshatch pattern with white dots centered in each square appears on the screen. (The grid is enclosed by a red rectangle.) The center part of each side of the red rectangle should be 1/4 inch behind the bezel, out of view. Use this pattern for convergence and white balance. -- 7/// Stephen Ryner, Jr. TLT "Keep Pedaling!" When cryptography is outlawed, - rynersw@indiana.edu bayl bhgynjf jvyy unir cevinpl.
