Radial type of parallel system bus structure having pairs of conductor lines with impedance matching elements

Abstract

An improvement in a radial-and-parallel bus structure which includes a stack assembly of bus-printed disks whose centers are arranged on common center axis. Each bus-printed disk consists of a disk of dielectric material bearing on each of its opposite major surfaces, a printed radial pattern including a plurality of printed signal conductors of equal length radially extending from the center of the disk. Each signal conductor on one of the opposite major surfaces of the disk is coupled to a corresponding signal conductor on the other major surface to make up a signal conductor pair, and every signal conductor pair is terminated with an impedance matching element which is adapted to be connected to a selected lead in a selected one of CPU boards standing upright around the stack assembly of bus-printed disks. The impedance matching element prevents signal reflections of data being transmitted between selected CPU boards.
