Reported herein is the modification of a monoproccessing operating system, UNIX, designed to support an interactive multiprogramming environment on the PDP 11/40, 11/45 and 11/50 computers,' to a multiprocessing operating system utilizing two PDP 11/50 processors and an expanded set of peripheral devices. The evolution of change from UNIX to the more responsive and efficient modified version called MUNIX is documented here to provide a basis for continuing work on the system and as a guide that might prove helpful to others engaged in similar projects. MUNIX, while retaining all the qualities of UNIX, provides increased system efficiency and improved response to users. Although the project is considered a success the full potential of MUNIX is far from being realized. Towards this end several suggestions for improvement are made in the closing chapter.
