2357	 MUX a Simple Approach to On-Line Computing	 An on-line system operating as part of a normal batch system for the CDC computer is described. The system which required one man-year for initial software implementation although basically simple provides the necessary elements to input and modify files submit them for batch execution and provide results at the user s terminal. A multiplexer designed and developed as part of the project cost one man-year for design and checkout and for parts and fabrication. All aspects of the system are described including design criteria implementation cost overhead and user reactions. time-sharing remote computing on-line access on-line computing remote file manager real time multiplexer implementation effort operating overhead user reactions remote terminals operating system
