Abstract
Pleiades, a seven-user, real-time-sharing executive was developed on a PDP-15 computer for control of psychological experiments. The goal of the system development was to provide millisecond timing accuracy for all users and to permit easy computer utilization for the novice user. Two modes of operation are available: the standard language approach and the experiment writer approach. The system is discussed from the user’s viewpoint, and a brief description of the details of system design is given. The system has been operating successfully for several months.
