Simulating operating systems
P. H. Seaman, R. C. Soucy · IBM Systems Journal · 1969
The operating system models have been used for both development and installation work. They can be modified to simulate the effect of a proposed change, as well as simulating the activity of a specific Configuration of equipment to be installed. Since the models are miniature systems, they can serve as an educational tool, to elucidate the functions of the operating system and its relationship to user programs. The models have been written for general use. However, feedback from the pilot users indicates that two versions of the same package are really required: a detailed version similar to that described above, and a gross version with additional input options.
