Alteration and Implementation of the CP/M-86 Operating System for a Multi-User Environment.
Abstract
CP/M-86 is a single user microcomputer operating system. This thesis provides a multi-user protected CP/M-86 based disk sharing environment consisting of four Intel iSBC 86/12A single board computers, a MMB-80 bubble memory, and the REMEX Data Warehouse 3200 memory storage unit. The REMEX houses a 14 inch Winchester hard disk and two flexible floppy disk drives providing in excess of 20 megabytes of data storage capacity. The major objective in the design of this system was to create a table-driven CP/M-86 Basic Input/Output System that could be quickly and easily reconfigured to adapt to any new hardware configuration. Once the system was operational, the REMEX hard disk could then serve as a signal processor emulation for the AEGIS system. By making direct calls to the appropriate read/write routines, stored radar data could be retrieved from the hard disk for use by the other system processes. (Author)
