Computer engineering laboratory microcomputer implementation

The phenomenal growth in the community of computer users has focused attention on single user microcomputers as a means of alleviating overcrowding on multi-user mainframes. This thesis concerns the development of a microcomputer· for the Virginia Tech Computer Engineering Laboratory. The primary objective was to upgrade the presently used monitor level microprocessor stations to full fledged microcomputers with a comprehensive operating system. As a part of the overall study, dynamic RAM system design using VLSI controllers was investigated. A comparison of two popular controllers is presented. Another aspect investigated is floppy disk control strategies. A comprehensive analysis of various schemes is provided. A conclusion based on applicability and performance of the microcomputer developed is drawn and suggestions to further enhance its utility are made.
