Television game console and electronic control device for controlling the allowable playing time of the television game console

摘要

A television game console has a central processing unit and an electronic control device for controlling the allowable playing time of the television game console. The electronic control device includes a timer control device which interfaces the central processing unit with a game cartridge read only memory unit. The timer control device has a current time clock output and receives a presettable allowable playing time range input from the central processing unit. The timer control device electrically connects the game cartridge read only memory unit and the central processing unit only when the current time clock output is within the allowable playing time range.
