Decus Proceedings

This document is a formal compilation of the papers and presentations delivered at the 1963 Spring Symposium and the Annual Meeting of the Digital Equipment Computer Users Society (DECUS). It provides an in-depth look at the state of computing on Digital's PDP-1, PDP-4, and related hardware in the early 1960s. The proceedings cover five main sections: Time Sharing, Utility Programs and Techniques, Problem-Oriented Techniques, Hardware and Input-Output Techniques, and an Appendix containing meeting programs and author indexes. Key themes include the development of time-sharing systems, on-line debugging techniques like DDT and its successor 'ID', graphical input devices for digitizing data, and the emergence of specialized software compilers such as DECAL and AMP. The volume serves as a historical record of the collaborative efforts and technological advancements shared by the early DEC user community.
