This important revision introduces both students and practicing computer professionals to the characteristics of the Motorola 68000 family of processors. It has been widely applauded in previous editions as a text that is practical, easy to read, and designed to educate readers on the concepts as well as applied theory. In addition to its use as a learning aid, the text serves as a valuable reference in which topics are organized according to function and importance for the design of programs, interfaces or systems. This Second Edition has been updated to cover the most recent, relevant advances and developments affecting the MC68000 family of microprocessors.

Covering routines for the most popular machines - ATT computer, the Atari 68000, the Commodore Amiga and the Macintosh - this book takes readers through all aspects of assembly language programming in a step-by-step fashion. It provides a complete, graduated approach to the entire line of 68000's, giving examples and exercises for each step so that readers can acquire all of the necessary skills. Topics include the 68000 programmer's model, explanations of number systems, subroutines and advanced assembler concepts, such as external references, linking, debugging and macros.

In the past several years, microprocessors have emerged as a major force in the computer industry, and the Motorola MC68000 family is regarded as an industry standard. The focus of this book is the Motorola MC68000 microprocessor family. Many of the design practices and fundamental concepts can apply to other modern microprocessors as well. This guide covers both the software and hardware of the M68000 family, and is designed as a text for a one-semester, junior-level microprocessor course that covers both programming and system design using the MC68000 microprocessor.
