For arcade enthusiasts and operators, maintaining and upgrading classic cabinets requires a specific set of parts. The most common accessories are those that either facilitate operation, replace worn-out components, or enhance the gameplay experience. Key peripherals include coin mechanisms and doors for commercial operation, which are vital for accepting payments. The control interface is another critical area, with arcade sticks (joysticks) and push buttons being among the most frequently replaced items due to wear and tear. For the display, replacement monitors or modern LCD conversions are common, especially as original CRT tubes age. Additionally, power supplies, JAMMA harnesses for wiring, and protective marquees and bezels are essential accessories for keeping these iconic machines functional and visually authentic for years to come.
