An implementation of a multiuser timeshared operating system for the Sycor 440 Clustered Terminal Processing System is described. Utilizing an 8080 microprocessor, this system provides a virtual operating environment consisting of a console device, eight floppy disk drives, and up to 32 virtual floppy disk images on a five megabyte movable-head disk. In addition, a Centronix serial printer is incorporated into the system as a edicated device for any one of up to four concurrent users. The operating system supports utility programs including an editor, assembler, and debugger which facilitate microcomputer program development at the Naval Postgraduate School.
