This paper is concerned with the application and implementation of virtual memory systems on mini-computers. The system constraints and their effect on the design parameters are discussed in detail and a general design philosophy is developed. A specific implementation, both software and hardware, of a virtual memory system on a PDP-11/20 is described. The final system makes a machine with 8K of core and a small disk appear to the user as an off-the-shelf 32K computer with the capability of banking as many 32K sections as the disk can support. Memory protection is also available.
