Abstract

A simulated MIX computer system plays a major role in the undergraduate computer sciences curriculum of The University of Texas at Austin. Use of the simulated machine was adopted because it provides a more complete environment for teaching operating systems concepts while at the same time providing a simpler yet conceptually complete environment for teaching assembly language programming than do the available CDC 6000 series computers. The simulated system appears to also be more cost effective than the actual machines. The MIX system in use provides a full implementation of the original specifications with some extensions. Full concurrency of I/O and CPU operation is simulated with magnetic tape, disk, drum, and unit record devices. Experience with the system in courses has been very good. Several extensions of the system to enhance its usefulness in meeting course goals are discussed. The primary outcome of these extensions will be a very sophisticated simulated system whose image to the user will be "real" in every respect except for its physical existence.
