Logic Design of a Shared Disk System in a Multi-Micro Computer Environment.

Abstract

This thesis describes the detailed interface design and implementation of the Micropolis 1220 rigid disk storage unit into the AEGIS multiuser environment. At the onset of this work, the AEGIS development system consisted of an MBB-80 bubble memory, the REMEX Data Warehouse disk system, and four INTEL iSBC 86/12A single board computers. The micropolis interface was accompllished utilizing the INTEL 8255 programmable parallel I/O port resident on one of the AEGIS iSBC 86/12A computers. The iSBC 86/12A used for the interface can still be operated as an independent computer with all Micropolis disk operations being transparent to the user. The Micropolis disk unit adds an additional 35.6 megabytes of online storage to the AEGIS system. Utilization of the Micropolis disk system as a software development storage media will free the REMEX Data Warehouse for storage of radar data to emulate the SPY-1A radar.
