RSX-11: A family of [Real-time operating system]]s mainly for PDP-11 computers created by DEC, common in the late 1970s and early 1980s, designed for and much used in process control, but also popular for program development.

It existed in many versions:

  • RSX-11/D -- the original, used as the operating system on the small PDP-11 used as a boot device on the giant Decsystem 10 and DECsystem 20.
  • RSX-11M -- a multiuser version that was popular for the larger PDP-11s.
  • RSX-11M-Plus -- a much extended version of RSX-11M, originally designed to support the multi-processor PDP-11/74, a computer that was never released, but also used widely as a standard operating system on the PDP-11/70. The first to include DCL (Digital Command Language).
  • RSX-11S -- a memory-resident version used in real-time applications.
  • Micro/RSX -- a stripped-down version implemented specifically for the Micro PDP-11, a low-cost multi-user system in a box, featuring ease of installation, no system generation, and a special documentation set.

Dave Cutler was the chief designer of all these systems. Principles first tried here later appeared in DEC's VMS and Microsoft's Windows NT systems.
