ABSTRACT:
This invention relates to personal computers, and more particularly to a personal computer system having an Input/Output (I/O) controller which imparts flexibility to the system design and operation. The I/O controller has a plurality of segments. A first segment provides a serial port for exchange of data signals; a second segment provides a parallel port for exchange of data signals; and a third segment provides a selectable interface for connection with a selected one of said option bus and said planar I/O bus. The third segment has a signal line for transmission of a feedback signal indicative of a readiness for transfer of data signals through one of said first and second segments.
