ABSTRACT:
A radial type of parallel system bus structure used bus wire-printed disks each having printed signal conductors of equal length extending radially from a common contact center. Each printed signal conductor comprises two twisted conductor lines, and each conductor line consists of many segments disposed alternately on opposite surfaces of the disk, the successive segments of each line being connected by plating in through-holes in the disk. The radial arrangement of signal conductors permits connection of selected CPU boards via equal length of signal path. Also, the use of twisted conductor lines improves the signal transmission characteristics of the bus in high-frequency ranges.
