The OPS-1 Manual
(1964-05)
The recent attainment and continuing development of personally accessible computer facilities have opened another chapter in the use of machines by man. A number of current research efforts, including Project MAC at M.I.T., ...
Program Structure in a Multi-access Computer
(1964-05)
A multi-access computer (MAC) system consists of processing units and directly addressable main memory in which procedure information is interpreted as sequences of operations on data, a system of terminal devices ...
The MAC System: A Progress Report
(1964-10)
The notion of machine-aided cognition implies an intimate collaboration between a human user and a computer in a real-time dialogue on the solution of a problem, in which the two parties contribute their best capabilities. ...
Verbal and Graphical Language for the AED System: A Progress Report
(1964-05)
For Computer-Aided Design, use of time-sharing a single language which can take either verbal or graphical form is required. This paper describes how a single language processing technique, which is in turn a special ...
A New Methodology for Computer Simulation
(1964-10)
Computer simulation is a cooperative venture between researcher and information processor, but the processor's role customarily begins too late. The researcher can benefit substantially by bringing the computer up into ...
Natural Language Input for a Computer Problem Solving System
(1964-09)
The STUDENT problem solving system, programmed in LISP, accepts as input a comfortable but restricted subset of English which can express a wide variety of algebra story problems. STUDENT finds the solution to a large ...
SIR: A Computer Program for Semantic Information Retrieval
(1964-06)
SIR is a computer system, programmed in the LISP language, which accepts information and answers questions expressed in a restricted form of English. This system demonstrates what can reasonably be called an ability to ...
System Requirements for Multiple -Access, Time-shared Computers
(1964-05)
It is now clear that it is possible to create a general-purpose time-shared multiple access system on most contemporary computers. However, it is equally clear that none of the existent computers are well designed for ...
OPL-I An Open Ended Programming System Within CTSS
(1964-01)
OPL-1, an incremental programming system presently operating with CTSS, permits the user to augment both his program and his data base during widely separated successive sessions at his terminal. Facilities are provided ...
Use of CTSS in a Teaching Environment
(1964-11)
Computer time-sharing offers many interesting possibilities for use in teaching computer technology. It might be expected that with proper hardware and software, students using time-sharing as a teaching machine could ...
