Abstract
The design and implementation of an operating system for microcomputers based on Zilog
Corporation's Z80A, 8-bit microprocessor is herein discussed. The operating system manages
efficiently, the microcomputer system resources, such as the memory processor, input-output
system devices and information by keeping track of the microcomputer resources, resolving
conflicts, allocating and reclaiming system resources at the end of the allocated time.
This simple-to-use, small memory based and powerful operating system incorporates an
enhanced BASIC Language Interpreter: The features of this enhanced BASIC include good file
management system, powerful input and output statements for the Visual Display Unit (VDU)
layout, and high computational power.
The operating system also allow data transfer through serial and parallel ports using both
international and non-standard communication protocols. This allows access directly to either
systems or application programs of other popular microcomputers of different manufacturers
such as Commordore's PET, Apple Computer's APPLE II and Radio Shack's TRS-80.
