Decus Proceedings, Fall 1968

This document is the official proceedings of the Fall 1968 Symposium of the Digital Equipment Computer Users' Society (DECUS), held in San Francisco, California, on December 12-14, 1968. With a record-breaking attendance of 390, the symposium included a variety of technical sessions, papers, and workshops.

The content is organized into several key technical areas:

• Data Acquisition and Control: Includes papers on manufacturing processes (e.g., tantalum thin-film attenuators), gas chromatography systems (GasChrom-8), NMR spectroscopy, mass spectrometry data acquisition, and meteorological monitoring using PDP computers.
• Interactive Systems: Features papers on seismic data analysis consoles, coordinate measuring machines (CMM) for numerical control tape production, and terminal communications packages.
• Education: Covers computer-assisted instruction (CAI) systems, including the Huntington Computer Project and the use of CINET-BASIC in the classroom.
• Biomedicine: Includes research on patient record systems (ARBUS), laboratory information systems, evoked potential measurements in clinical neuropsychiatry, and ultrasound irradiation of the brain for research.
• Modules/Hardware: Details the development of modular interfaces, specifically focusing on M-series logic for PDP-9 computers, as well as workshops for PDP-8, PDP-9, and PDP-6/10 systems.
• Appendices: Provides an author/speaker index, a list of meeting attendees, and references to papers presented but not submitted for full publication.

The document serves as a comprehensive record of the technical advancements, software developments, and experimental applications of Digital Equipment Corporation (DEC) hardware during that period.
