The Project C-BE plan for a data communications system is designed to support a dedicated minicomputer time-shared system for undergraduate use. The system is flexible and accepts a wide variety of terminal devices for a broad range of course materials. Provision is made for expansion and updating of equipment and data, and a commonly supported transmission code (ASCII) will be compatible now and in the future. Extended BASIC is the programing language used by undergraduates throughout the system. (CH)
