Microcomputer control of behavior and the acquisition of digital and analog data

Advances in technology and decreasing costs are enabling microcomputers to displace more traditional devices in the scientific laboratory. The availability of various approaches to software-system development for the use of microcomputers in the on-line control of experiments has contributed to the trend. This report describes a software system developed to control conditioned behavior during schedules of reinforcement while simultaneously accumulating behavioral data and physiological (analog) data using a hardware system based on the Radio Shack TRS-80 Model I microcomputer. The software utilizes a high-level interpretive language (Microsoft BASIC), assembly language and compiled BASIC to attain an acceptable execution speed and ease of programming.
