Abstract

Disclosed is a bus extension system which is capable of bidirectionally coupling a basic bus and an extended bus without using a dedicated control circuit on each functional card attached thereto, but using a single bus extension card interposed between the basic bus and the extended bus. The present bus extension system does not require any termination card which has been customarily used in the prior systems to terminate the basic or extended bus at its remote end. Referring to Fig. 1, there is shown the bus extension card interposed between the basic bus and the extended bus, each being adapted for bidirectionally transferring address, data and control signals.
