Segmented backplane for multiple microprocessing modules
First Claim
1. A segmented computer backplane adapted to have one or more printed circuit cards connected to it, said backplane forming a single unitary bus and backplane structure made up of a plurality of physically separable but interconnected backplane segments, each backplane segment comprising:
- a plurality of connecting means for respectively connecting a plurality of said cards to said backplane segment;
a plurality of fixed electrical interconnections for making connections to and between said plurality of connecting means, said connections being completely established within said backplane segment irrespective of whether said cards are actually inserted into said connecting means;
a bus segment which is removably connected with other bs segments of other backplane segments to form a unitary bus; and
a bus segment connector adapted to connect said bus segment of said backplane segment to the bus segment of another backplane segment to form a unitary bus and backplane, said plurality of connected cards carrying out electrical communication among themselves entirely through the said plurality of fixed electrical interconnections of their own backplane segment without communication through said bus, whereby said connected backplane segments form a unitary backplane having its inter-segment communication carried out through said single unitary bus.

Abstract
The invention relates to a novel type of segmented backplane for multiple microprocessor module boards. The modules are connected to a plurality of backplane segments. Each backplane segment includes connectors for attachment of the microprocessing modules, and a bus segment. When the backplane segments are connected together, the bus segments form a continuous bus. The microprocessing modules carry out their intra-module communication entirely within their own backplane segment without communication through the bus. However, all inter-module communication is carried out through the bus.
