The PLATO IV Architecture.
Stifle, Jack
The PLATO IV computer-based instructional system consists of a large scale centrally located CDC 6400 computer and a large number of remote student terminals. This is a brief and general description of the proposed input/output hardware necessary to interface the student terminals with the computer's central processing unit (CPU) using available transmission techniques, i.e., dedicated telephone lines and cable television (CATV) lines. The output controller is basically a parallel to serial converter which accepts data from the computer and encodes the data into a form compatible with the requirements of commercial CATV equipment. The input controller scans incoming lines from the terminals for data and controls the flow of that data to the computer. A peripheral processing unit controls the operation of the input controller with external function codes. A keyset multiplexor allows up to 32 PLATO IV terminals to share a common data line to the computer. (Author/JY)
