The Development of an On-Line Laboratory for CAI and Behavioral Research (1964-1968). Technical Report.
Judd, Wilson A.
Psychologists and educational researchers who may be interested in installing a computer system in a behavioral science laboratory may learn from the experience gained in the development and operation of the Computer Facility at the Learning and Research Development Center of the University of Pittsburgh. Built around a PDP-7 computer, using a system designed much like an early process control system, the Facility in 1969 developed a new time-sharing system, the LRDC Experimental Time-Sharing System (ETSS). The elements of its hardware are explained: main frame, information transmission device control, automatic priority interrup system, multiplexor, clocks, relays and buffers, PDP-7/PDP-9 interface, input-output devices, subject terminals, and remote terminals. The various aspects of the software are also explained: jobs and job scheduling, master tables, memory management, operator control, input/output device routines, stimulus device control routines, response device control routines, utility programs, and higher-level languages. The physical plant is described and personnel duties listed. A description of 12 experimental control programs is provided. The importance of documentation is emphasized and appendices illustrate documentation undertaken. Practical advice and references are given. (MF)
