Abstract
The invention is a multi-port video game controller interface which provides supports for at least two multifunctional game controllers via a single microcomputer I/O bus connector. An address decoder selectively enables one of the game controllers, in order to access the control input received therefrom. A program operating in the personal computer polls separate addresses within the game controller address space to receive input information from the different controllers. Jumper blocks map each of the plurality of controllers to separate and distinct addresses, in order to avoid address conflicts and provide flexibility.
