A general principle that any devices and computers embedded in a system should be considered in equal rights is established. This principle suggests a good simulation technique of a computer controlled system, offering simplicity and flexibility. For demonstration, simulation of minicomputer system is implemented for a purpose of developing and debugging real programs, especially those sensitive to input-output interrupting timing. The simulation technique described can be applied for large computer system to investigate the system efficiency.
