RSTS/E

Operating System

RSTS is a multi-user time sharing operating system that Digital Equipment Corporation built for its PDP-11 minicomputers, first implemented in 1970, with its final version, RSTS/E 10.1, shipped in September 1992. DEC sold its PDP-11 software business in 1994, after which Mentec continued supporting later versions. The system ran only on PDP-11 hardware, from the PDP-11/20 through the PDP-11/70, was written mainly in MACRO-11 assembly language with its utilities in BASIC-PLUS, and could support up to 128 terminals and 63 concurrent jobs. Memory support grew from 56 kilobytes in early versions to 4 megabytes in later ones, and starting with version 9 it added the Digital Command Language as its primary command interface, alongside support for FORTRAN, COBOL and DIBOL through runtime emulation.

FAQs

What was RSTS/E used for?

It served timesharing users and batch jobs and was used for program development and special purpose applications.

RSTS/E was a general purpose system rather than a single-purpose one. It could be used for interactive timesharing, for batch processing, for indirect command file processing and for program development in a variety of languages and tools. It also ran a wide variety of special purpose applications. Many people could work on it at once: with multi-terminal services it supported up to 127 concurrent terminal users, local and remote, and without multi-terminal services the maximum was 63 users. Tasks on the system could share computational, storage and input and output services.
