JANUS/ADA Software Implementation of a Star Cluster Local Area Network of Personal Computers

Abstract

This thesis describes the detailed design and implementation of a star cluster local area network among multiple Zenith Z-100 microcomputers. The Z-100s are linked together by the Concentrator, a server system consisting of a power supply, an iSBC 86/12A single board computer, and three BLC 8538 eight channel I/O expansion boards, through RS232c USART ports. The local area network software consists of a server program resident in the Concentrator which provides the communication links between the Z-100s and the utility programs resident in each microcomputer. These utilities include file and message transfer (both point to point and broadcast), directory listing transfer, and online user identification. The program and utilities are written in JANUS/Ada, with assembly language sub-routines for machine specific functions, and are designed run with the CP/M-86 operating system.
