Abstract
ABS: AN APPLICATION LANGUAGE FOR PSYCHOPHYSIOLOGICAL EXPERIMENTATION IBM 1130 (8K) Acronym: ABS (Adaptive Bio‐Signal Language). Machine Sensible Materials: Preamplified biosignals. Documentation: Operating manual (80 pp. German). Author: F. Gerster. Submitted by: H. Legewie Submitter's Affiliation: Max‐Planck‐Institut für Psychiatric, Munich, Federal Republic of GermanyABS is an application language for biosignal processing and experimental control. It is running on an IBM 1130 which is connected to a WDV Lab Interface which allows biosignal input and process control output and which serves as a realtime clock. ABS is implemented on the basis of the IBM 1130/1800 macro assembler, so it can be adapted to an IBM 1800 with slight modifications.It allows the easy programming of individual ABS programs to solve a set of problems in psychophysiological experimentation: On‐line acquisition and reduction of biosignals from up to 20 input channels, including 4 channels of EEG; simultaneous experimental control by simple statement for time scheduling, control of the output channels, logic and arithmetic operations applied to the reduced biosignals for feedback functions; facilities for on‐line interaction with the experimenter and for on‐line testing: organization of a complete data file of the experiment on a background storage device. Minimum Hardware: IBM 1130 (8K core and 520K disc), WDV Laboratory Interface1 realtime clock, 8 analog, 8 digital, 4 trigger input channels; digital mag tape optional.
