Midway 4-Player 25" Dedicated Video Game manual Menu System, Control Functions

MENU SYSTEM

WHAT IS THE MENU SYSTEM?

The game’s Menu System is a series of auditing, game adjustment and diagnostic screens. We call these screens menus, because they present options in menu-like lists. You can easily access and apply menus to optimize game performance. For instance…

•Use game audits menus to assess game performance.

•Use adjustment menus to help you to customize game performance. For instance, you can restore factory default game settings. You can also calibrate player controls for accuracy.

•Use diagnostic menus to verify proper equipment operation.

ACTIVATING THE MENU SYSTEM

Open the coin door. Find the TEST MODE switch inside. Press TEST MODE to invoke the Menu System. The game system responds by exiting Game Mode and entering Diagnostic Mode. You can also invoke the Menu System by turning on DIP bank U12, switch 8. (To reenter Game Mode, turn off switch 8.)

AUTOMATIC TESTS

In Diagnostic Mode, the Power-On Self-Test (POST) activates. This routine runs automatically. It can detect faults that cause game or Menu System malfunctions. POST usually takes less than a minute. The test doesn’t display anything. Instead, the system boot loader indicates the software revision number and serial numbers. The system boot loader also displays a sound-loading message and other useful information.

At the end of POST, the system displays the Control Functions Menu.

CONTROL FUNCTIONS

The Control Functions Menu is purely informational. It appears for five seconds. Then the Menu System automatically displays the Dual Game Adjustment Menu.

The Control Functions Menu introduces the menu navigation controls. The key point is that you can use either player or diagnostic controls to navigate menus. Diagnostic control switches are particularly helpful when you must troubleshoot player switches. This manual discusses the controls in more detail in this chapter’s Main Menu section. Also see the page on the menu that interests you.
