For the next two purposes, we made hardware units for data communication among computers. One is to support the study on computer complex systems and the other is to enhance function of our computer system. There are three hardware units for data communication among computers, which are OCU, UCU and CCA. OCU communicats between OKITAC 4300 and FACOM U-200 by program mode, UCU and CCA communicat two FACOM U-200 s and FACOM 230-45 S and FACOM U-200 by direct memory access mode, CCA was prepared by FUJITSU Company. The data transfer rates of OCU, UCU and CCA are 300,800 and 250 kilobytes/sec. respectively. In this paper we describe the design policies and the circuit diagrams of OCU and UCU, and explain how to use OCU, UCU and CCA. These communication systems are useful in some fields such as computer complex systems, speech synthesis and recognition, and sharing of resources.
