摘要:
The cost and complexity of connecting electrically actuated devices to a game control microprocessor in a coin operated amusement game can be reduced by utilizing a standard control assembly including a memory element for each of the devices and where a control circuit is used to connect the assemblies in series with the microprocessor. Data and clock lines in the control circuit are used to transmit control signals to the devices and the control circuit can additionally include power supply lines and a ground line. A similar arrangement can be used to transport data representing the status of game operated switches to the microprocessor.
