In this paper, we describe the implementation of a desktop CSCW (Computer Supported Cooperative Work) system using commercially available consumer electronic devices and facilities. The system is developed on workstations under UNIX and OPEN LOOK environments connected by FDDI (Fiber Distributed Data Interface) networks. It provides multiparty conference with shared white board. shared test editor, calendar, and voting capability. Each conference with these features can support a groupware environment. The design and consideration of the framework of the system is presented. During the implementation, some performance issues, such as error control, medium synchronization and throughput improvement will also be discussed.
