Multi-computer access switching system

A multi-computer access switching system for accessing a plurality of computers from a single work center, said work center including input/out devices, said plurality of computers located at distinct physical locations substantially remote from said work center, said system comprising:

• a selector unit, including a designator to provide computer identification signals for selective communication between said work center and a selected one of said plurality of computers, said selector unit located at or near said work center and connected to said input/out devices of said work center;
• at least one controller unit, including switch elements for selectively connecting said selected one of said computers to said work center as indicated by said computer identification signals and located proximate said plurality of computers and connected to said computers;
• and
• a cable bus coupling said selector unit to said at least one controller unit to enable said work center to be selectively connected to one of said plurality of computers through said switch elements in accordance with said computer identification signals and to enable said selective communication between said work center and said selected computer through said same cable bus;
• wherein said designator in said selector unit includes a counter and a counter switch for actuating said counter to selectively identify said computers and provide said computer identification signals representative thereof and wherein said cable bus includes a plurality of signal paths to carry said computer identification signals.
