A vast increase in running speed can be obtained when using programs written in assembly language, which in essence entails direct programming of the computer without using a high level built-in language such as BASIC. However, this can only be undertaken by someone who has a reasonable understanding of the microprocessor and some of the other hardware used in the computer, but it is not as difficult as one might think and this book tells the story

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.

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.
