Design Expansion of the D17B Computer Facility.

摘要

Several years ago,the Electrical Engineering department of the Air Force Institute of Technology School of Engineering initiated a research program to investigate and demonstrate the feasibility of converting the Minuteman I ICBM D17B guidance computer into a general purpose minicomputer. This report,as part of a continuing effort to determine the extent to which the capabilities of the computer can be applied to a general-purpose information processing tasks,presents the results of a study of the memory writing circuitry of the machine. The study was conducted to investigate the possibility of installing a two-way Direct Memory Access (DMA) capability in the AFIT D17B. The study forms the basis for a design proposal for such a DMA facility for the AFIT D17B complex. This proposal is fully defined in register transfer language and other logic expressions before being presented in a hardware realization. (Author)
