DEC PDP-11
Realizes: interactive workstation time-sharing, general-purpose operating system development
The DEC PDP-11 married an unusually orthogonal instruction set with dual UNIBUS and DIBUS pathways, letting its transistorized backplane with microprogrammed control deliver interactive time-sharing workstations that popularized UNIX and RSX operating systems, while responsive DMA-friendly peripherals powered a generation of general-purpose CPU designs.
