Bus rack for accommodating plural stand-alone computers

The present invention includes a computer bus rack having a circuit board for accommodating a plurality of stand-alone computers. The circuit board has a front side and a back side, and the rack comprises a first plurality of slots coupled to the front side, and a second plurality of slots coupled to the back side. The first and second plurality of slots are arranged such that corresponding ones of the first and second plurality of slots are in alignment together. Also, a plurality of connectors are affixed to the circuit board in alignment with the first and second plurality of slots, and have respective pass-through connector-pins that extend into each of the first and second slots, wherein certain ones of the connector-pins allocated to carry power signals are commonly connected for each of the plurality of connectors, and remaining ones of the connector-pins with respect to a particular slot are electrically isolated from connector-pins with respect to another slot on the same one of the front side and the back side. Because the connector-pins of the slots in the present invention are not electrically connected to each other, except for the connector-pins carrying power signals, each slot acts as an isolated bus. This allows an independent stand-alone computer to be coupled to each slot of the circuit board.
