Multiple video boards of the general purpose type (e.g. EGA or VGA boards) and their associated monitors are operated by a single computer of the personal computer type, without modification of the computer hardware and while the video boards reside in their usual expansion slots which are provided by connectors on the mother board of the personal computer by a system which utilizes a flexible printed circuit board containing circuits which allows the processor (CPU) of the computer to present address and data signals which operate circuitry on the flexible boards to selectively enable or inhibit the communication of control signals (on the I/O and memory read and write control lines) to the video boards thereby enabling them to generate graphical images for their associated monitors. The signals on the address control and data lines are tapped and relayed either directly or after processing to the associated video board thereby enabling multiple video boards of the same or different types to be used concurrently by appropriate programming of the computer without the need to interchange hardware to switch between displays thereby reducing the inconvenience and potential hardware damage necessarily incident to such a hardware interchange procedure.
