Abstract : A special-purpose time-sharing executive program for the PDP-1 computer is described. Input-output transfers, multiple-user operation, inter-user communication and inter-module transfers are interpreted and performed by the executive program. Although the program reflects the hardware configuration of the Dynamic Experimental Processor (DX-1), the techniques used are applicable to other similarly-configured computer systems. (Author)
