Arcade machines utilize several standardized connectivity options that have evolved over decades. The most universal is the JAMMA (Japan Amusement Machine Manufacturers Association) standard, which uses a 56-pin edge connector that carries all necessary video, audio, power, and control signals through a single harness. This revolutionary system eliminated the need for manufacturer-specific wiring and became the industry benchmark from the mid-1980s onward.

For video output, most arcade cabinets employ standard RGB (Red, Green, Blue) signals through 15-pin connectors, though some older models used composite video. Modern conversions often incorporate VGA, HDMI, or component video interfaces for compatibility with contemporary displays. Monitor connections typically include separate sync lines for horizontal and vertical synchronization.

Control interfaces generally consist of simple direct-wired connections for buttons and joysticks, though some modern systems use USB encoders for PC-based arcade setups. Power distribution typically follows standardized AC voltage routing with isolation transformers for CRT monitors. Additional connectivity may include stereo audio amplifiers, coin door interfaces, and network connections for newer redemption or ticket-dispensing games.

Understanding these fundamental connectivity options is crucial for both arcade restoration and modern MAME cabinet construction, ensuring proper signal transmission and gameplay functionality across various arcade generations.
