A computer simulator for use in an introductory course on computer systems and assembly language programming

This paper describes a simulator for a computer system comprising a simple central processor, memory and a variety of peripheral devices. The simulator is used in the laboratory component of an introductory course on computer systems and assembly language programming. The simulator exploits the limited “cursor graphics” capabilities of commonly available display terminals; the graphics are used to present a view of the internal operations of the simulated computer.
