Troubleshooting Static Sensitive Devices

Certain precautions must be taken when working with static-sensitive devices, e.g., microprocessors, field-effect transistors (FET), complementary metal-oxide semiconductors (CMOS), and other large-scale integration (LSI) devices that use metal-oxide semiconductor (MOS) technology. Static charge buildup in a person's body or leakage from an improperly grounded soldering iron can cause static-sensitive device failure. Before handling a static-sensitive device or a PCB with such devices attached...

Motion Object Test

The Motion Object Test appears is shown in Figure 2-9. The Motion Object Test indicates the condition of the motion-object buffer circuit. There are fifty-six objects, eight pixels wide, placed in two rows in the center of the screen. The following information is provided at the bottom of the screen OBJECT indicates the number of the motion object selected. PICTURE indicates the stamp number in ROM. HORIZONTAL indicates the horizontal position of the object. VERTICAL indicates the vertical...

Press the left Start button, and the next display to appear should be green with the word GREEN displayed at the bottom of the screen. Press the left Start button to obtain a blue, white, and finally a grey screen. After the grey screen, the display will repeat the red, green, blue, white, and grey sequence again. If the display characteristics are not correct, refer to the display manual for the color-purity adjustment procedure or the possible cause of failure. Press the left Fire button to...

Ramrom Test

The RAM ROM Test screens are shown in Figures 2-1 and 2-2. This test provides a visual check of the game RAM, ROM, and associated circuitry. If the RAM and ROM Test passes, the display advances to the Switch Test. The RAM ROM Test is divided into two sections. The RAM Test is performed first. If the RAM Test passes after a six-second delay, the self-test skips to the ROM Test without displaying any message. If the RAM fails, a message will be displayed in the center of the screen as shown in...

Introduction

Xybots is a one- or two-player game with a continuous buy-in feature allowing players to join in at any time. A color-coded control panel (left player blue and right player green) and game character allows for instant identification by players. Each player controls a special joystick and two buttons. The joystick is eight-way directional with an independently turning knob for left and right turns. Players use a blaster to fire upon the many Xybots in the maze. A button is located on each side...

Removing Integrated Circuits

The easiest and safest method for removing soldered-in integrated circuits (IC) from a PCB is to cut off each pin as close to the IC case as possible with a tip dyke (diagonal cutter) as shown in Figure 4-1. Use the proper soldering iron as previously described under Soldering Techniques. Then, to avoid excessive heat buildup in one area of the PCB, apply heat directly to each pin in a random order. Remove the loosened pin with the tip of the soldering iron or a needle-nose pliers as shown in...

Convergence Test

The Convergence Test is shown in Figure 2-13- This test indicates the condition of the display size, centering, linearity, and convergence. The grid pattern should be white. Press the left Start button and the grid pattern should turn violet. Pressing the left Start button again should cause the grid pattern to turn green. Check the grid pattern for good, the word GOOD should appear. If the sound microprocessor or associated circuitry is faulty, a number will appear (to indicate sound status)...

Maximizing Earnings

Operator options on this game have been kept very simple. You should thoroughly read Chapter 2, Self-Test, for the Coin Options, Game Options, Histograms, and Statistics screens so that you can effectively use the available options. Use the Self-Test screens showing Statistics and Histograms to evaluate game data, and the Game Options screen to make adjustments. (Refer also to the Self-Test chapter for more information on setting options.) The key to maximum earnings is striking a midpoint on...

Self Test

The Xybots game tests itself and provides visual and audible indications of the condition of the game circuitry and controls. Self-test information is displayed on the screen and through the sound system. No additional equipment is required. We suggest that you perform a self-test when you first set up the game, each time you collect the money, or when you suspect game failure. Thirteen self-test screens provide information pertaining to the game circuits and controls. The game enters the...
