An arcade machine consists of empty box, picture tube, scanning base, power supply box, transformer,a cable, joystick, micro-movement, Arcade Button, Coin Acceptor, speaker, lamp holder, lamp and exhaust fan.
A normal arcade machine consists of a Game PCB Board, a cassette switch power supply, a coin acceptor, a control button board, a scanning board, a video tube, a speaker and a slot, etc. Some machines also have a coin refunder. The computer board is the heart of the machine and receives signals from the control keypad and coin acceptor.
The computer board is the core part of the whole game machine, it mainly includes four parts: graphics memory, graphics processor, command memory, command processor, graphics processor is a microprocessor, it will be stored in digital form in the graphics memory graphics information into analog signals (including graphics, colour, brightness and other signals), these signals are then transmitted to the scanning board, converted into video signals sent to the fluorescent screen The graphics processor also converts the digital sound signal into an analogue signal, which is sent to an amplifier to produce sound through the speakers. The command processor is also a microprocessor, which reads commands from the command memory and determines the signals coming from the operating handle to control the graphics processor to display different screens and make different sounds. This is why you cannot have a console without a computer board.
