The hardware architecture of an arcade game machine is a carefully designed system that ensures smooth gameplay and an immersive experience. Here are the key components that make up its structure:

1. Printed Circuit Board (PCB): The heart of the machine, the PCB houses the game’s software and controls all hardware interactions.

2. Display Unit: Traditional arcades use CRT monitors for their fast response times, while modern machines may feature LCD or LED screens.

3. Control Panel: Includes joysticks, buttons, and trackballs, allowing players to interact with the game.

4. Sound System: Amplifiers and speakers deliver high-quality audio effects and music to enhance gameplay.

5. Power Supply Unit (PSU): Provides stable electricity to all components, ensuring consistent performance.

6. Coin Mechanism (Optional): In commercial arcades, a coin slot or card reader facilitates pay-to-play functionality.

These components work together to create the classic arcade experience, blending hardware precision with engaging gameplay.
