The basic hardware configuration of a network of up to 17 TRS-80 microcomputer systems (1 central, 16 peripheral) is described as implemented in the psychology department at the University of British Columbia. Such a system can serve several instructional functions (e.g., data generation for lab experiments, simulation of theories or experiments, hands-on practice in independent research, interactive graphics display of difficult concepts) in a wide variety of psychology courses, including introductory, experimental, quantitative methods, perception, cognition, and advanced lab courses. It can function either as a block-scheduled research experience for large courses, as a drop-in research utility for advanced lab courses, or as a utility for data collection in course projects in research methods or lab courses at both undergraduate and graduate levels. A wide variety of software is already available for this system, and other software can be readily adapted or developed out of computer programs used for research or lab exercises. Some disadvantages in comparison to other systems include weak graphics and a lack of concern about upward compatibility of older devices with newer products. Several recommended books and utilities are listed, and six figures, including a diagram of the network, are appended. (Author/MER)
