ISIS (operating system)

ISIS, short for Intel System Implementation Supervisor, was an operating system for early Intel microprocessors such as the 8080. It was developed by Ken Burgett and Jim Stein under the management of Steve Hanna and Terry Opdendyk for the Intel Microprocessor Development System, starting in 1975, and a later version, ISIS-II, served as the operating system for the PL/M compiler, assembler, link editor and In-Circuit Emulator; it was developed on an early prototype of the same MDS 800 hardware that Gary Kildall used to develop CP/M.
