MUX, a simple approach to on-line computing


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.

Shape the Future of Computing

ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.

Get Involved

Communications of the ACM (CACM) is now a fully Open Access publication.

By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
