Abstract
CP/M-ee is a single user rriicrocomputer operating system
developed by Digital Research. This thesis provides a
multi-user "protected" CP/M-86 based disic sharing
environment consisting of four Intel iSBC a6/12A single
board computers, a MBB-60 bubble memory, and the REr^EX Data
*arehouse 3223 memory storage unit. The REMEX houses a 14:
incn Winchester hard diszc and two flexible floppy disic
drives providing in excess of 23 megabytes of data storage
capacity. The major objective in the design of this system
was to create a table-driven CP/M-66 Basic Input/Output
System that could be quickly and easily reconfigured to
adapt to any new hardware configuration. Once the system
was operational, the ESM3X hard distc could then serve as a
"signal processor" emulation for tne AEGIS system. 3y
maKing direct calls to the appropriate read/write routines,
stored "radar data" could be retrieved from the hard disi
for use by the other system processes.
