Abstract

PURPOSE: To make it possible to make the print board insertion position arbitrary by making connector pin positions for respective signal lines common in respect to common signal lines and adopting an on-board connector to connect signal lines other than common signal lines to this connector.
CONSTITUTION: The micro computer system is constituted by CPU board 1, memory board 2, process I/O board 3 and external I/O device 4. Standardized products are used as board connectors 8A, 8B and 8C, and sequential numbers are added to them, and signal lines corresponding to them respectively are determined previously, and pin positions are made common. Thus, boards are not specified by the correspondence relation among boards 1 to 3, and the system is operated whichever board of connectors 8A to 8C is inserted. Then, since the relation of I/O signal busses 9 is mounted on on-board connector 10 of the different system, all troubles about the connection relation of connectors are solved.
