Decus Proceedings 1963

This document contains the proceedings of the 1963 meetings held by the Digital Equipment Computer Users Society (DECUS). It serves as a collection of papers and presentations that highlight the advancements, research, and technical implementations utilizing Digital Equipment Corporation’s PDP-1, PDP-4, and related systems at the time.

Key themes and sections include:

• Time Sharing: The proceedings emphasize the fundamental shifts in computing toward "memory sharing" rather than just "time sharing." Several papers detail early implementations of time-sharing systems at institutions like BBN, Stanford, SDC, and M.I.T. (Project MAC).
• Utility Programs and Techniques: Papers cover improvements to debugging tools like DDT, symbolic modification programs at compile-time (DECAL), and versatile programming systems for large installations.
• Problem-Oriented Techniques: These presentations discuss applying PDP-1 systems to specialized research, including nuclear particle track analysis (SPASS/PIP), speech research, small group behavior simulation, and number theory.
• Hardware and I/O Techniques: This section focuses on hardware-level developments, such as the Microtape system, graphical input devices (e.g., pen and gimbal systems), and hybrid computation facilities combining digital and analog computers for real-time simulations.

The volume also includes administrative information for DECUS, such as officer lists for the 1961–1963 periods, meeting programs for the Spring and Annual events, and author indices.
