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.
