Floppy disk controller for M6800 based system

Abstract

The purpose of the thesis is to design and realize a single density floppy disk controller, in order to extend and increase the capacity and capabilities of a M6800 based microcomputer system. In order to create a powerful microcomputer, an operating system software is adopted to gain the features of a development system. The floppy disk controller can be wieved as a module for an existing system; however, the aim of the thesis is not only to add a module, but to integrate ihe controller, the central processing unit, and the operating system to achieve the full microcomputer. A memory module is incorporated to increase capacity, and group memory elements on a single board. To lower component cost the hardware is minimized and all possible controls are left to the software. The devIelopment system can be used for editing and entering programs, converting assembly or high level language programs to machine code by using as semblers and compilers, running these machine code programs, and linking separate programs to create the software of different kinds of microprocessor products.
