A Shared Environment for Microcomputer System Development.

Abstract

A timeshared microcomputer monitor for Intel 8080 microprocessor systems development has been described. Running on the Sycor 440 Clustered Terminal Processing System, the monitor provides a virtual environment composed of a console device, eight floppy disk drives, and an 8080 microprocessor for up to four concurrent users. Virtual floppy disk files on a five megabyte movable-head disk provide the system's primary auxiliary storage medium. Three different levels of access protection are available for these virtual floppy disk images. A command language processor has been included to support on-line modification of the virtual environment. System recovery in the event of a hardware or software failure is also supported by the monitor. (Author)
