An on-line system operating as part of a normal batch system for the CDC 6600 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 $16,000 for parts and fabrication. All aspects of the system are described, including design criteria, implementation, cost, overhead, and user reactions.
