RSTS/E Operating System

💾 RSTS/E: The Evolution of a Time-Sharing Legend Outlines the history and technical architecture of RSTS, a multi-user time-sharing operating system created by Digital Equipment Corporation for PDP-11 minicomputers. First launched in 1970, the system evolved from a specialized BASIC-based environment into a sophisticated platform supporting multiple run-time systems and the Digital Command Language. The documentation details how the software transitioned through various versions, eventually allowing for expanded memory addressing and interprocess communication before its final release in 1992. Technical features described include concise command languages, diverse terminal connection methods, and unique file protection systems based on project-programmer numbers. Additionally, the source covers the system's legacy, including its transfer to Mentec, the existence of hobbyist licenses for emulators, and several internal "easter eggs" like the "stardate" display. This overview serves as a comprehensive record of one of the foundational operating systems used in early 16-bit computing.
