The input-output system of the Lincoln TX-2 computer contains a variety of input-output devices suitable for general research and control applications. The system is designed in such a way that several input-output devices may be operated simultaneously. Since the computer is experimental in nature, and changes in the complement of input-output devices are(More)
The Lincoln Reckoner is a time-shared system for on-line use in scientific and engineering research. It looks forward to the day when a computational service can be put into the office of every serious research worker, and it was designed as an experiment to find out what features of such a service will have an important effect on the amount of work the(More)
The past few years have seen a widespread and growing application of packet-switched store-and-forward networks for data communication between geographically separated computer installations. Such networks can provide connections between facilities with the many desirable properties of dedicated communication lines but at reduced costs which result from the(More)
The TX-2 Computer, an experimental facility at M.I.T. Lincoln Laboratory, has been in operation since 1960. Never a service facility, the computer has been used principally in a number of long-term research projects that have taken advantage of the special input/output capabilities and the direct accessibility of the machine. These projects have included(More)
The TX-2 computer, an experimental machine at the M.I.T. Lincoln Laboratory, has been in operation for almost 10 years as an on-line, graphically oriented facility. In 1964, a time-sharing system for the TX-2 was started. This system, APEX, was to service a small number of consoles with graphic display capability. To achieve hardware economy, displays were(More)
"Coherent programming" refers to a set of conventions and techniques that we believe have the power to shape the growth of a library of programs, so that a user may draw upon them freely and with minimal concern about the details of their compatibility. The purpose of this paper is to explain the concept of coherence, and to show how it has been applied in(More)
A Call-by-Call SIMulator (CCSIM) of a switched communication network has been developed under the sponsorship of the Defense Information Systems Agency, It has been used for a variety of applications involving engineering and network management studies for the Defense Switched Network (DSN), undergoing a series of evolutionary extensions in the process. It(More)
