First published in 1984, this highly-rated guide written by 8-bit expert Mark Greenshields helped Commodore 64 users take their skills further than ever before. It was designed to take 'bedroom coders' from a point where they were comfortable with the commands - and limitations - of BASIC, to having knowledge and experience of the home computer's far more powerful machine code. In addition to explaining the concepts of this more advanced language, the reader is provided with a number of example programs that not only help with learning, but are also of great practical use for both games and utilities. This book helped many a Commodore user with their first steps into the world of machine code and to this day remains an important reference for those interested in the world of retro games and programming. * * * As the original publisher Interface Publications wrote: Now, you can master machine code on the Commodore 64 quickly and easily. Say goodbye to jerky, slow-moving graphics in BASIC, and learn the secrets of professional, incredibly swift graphic production in machine code. You're holding the first complete tutorial on using assembly language on the Commodore 64. The book assumes that although you can program in BASIC, you know little or nothing of 6502/6510 machine code. Step by simple step the book progresses through the subject, until the whole instruction set of the 6510 has been covered. A large number of example programs - which are explained in detail - help make the learning simple. In section two of the book, you'll learn about practical applications of machine code use on the Commodore 64. High resolution graphics, scrolling, raster graphics, using interrupts and adding commands to BASIC - they're all here in a form you can readily understand and apply. This section of the book contains programs which put 24 sprites on the screen at once, programs to combine both text and high-resolution images on the same screen, function key programming and one key entry of commands. Written by Mark Greenshields, highly successful author of Mastering the Commodore 64, this book is your gateway into the exciting world of machine code programming on the Commodore 64. * * * Acorn Books is proud to present its Retro Reproduction Series, a collection of classic computing works from the 1980s and 90s, lovingly reproduced in the 21st century. From standards of programming reference no self-respecting microcomputer user would want to be without, to obscure works not found in print anywhere else, these modern reprints are perfect for any connoisseur of retro computing.

First published in 1983, this user-friendly guide to the Commodore 64 helped many owners of the much-loved home computer understand their machine to a whole new level. The details within the book enabled users to go further than the confines of programming purely in BASIC and is still a highly useful guide for those interested in retro gaming on the classic machine. * * * As the original publisher Interface Publications wrote: This book is a manual for all Commodore 64 users who wish to increase their understanding of how their computer works and how to program it proficiently in BASIC and machine code. The author explains how sound and music synthesis, programmable characters, high resolution graphics, function key programming, animation and sprites are done in both BASIC and machine code. It also contains a full memory map of the Commodore 64 and explains how the full 64K can be used and how to correct errors in both BASIC and the KERNAL ROMs. * * * Acorn Books is proud to present its Retro Reproductions series, a collection of classic computing works from the 80s and 90s given a new lease of life in the 21st century. From standards of programming reference no self-respecting microcomputer coder would be without, to obscure works unavailable for many years, these modern re-prints are perfect for any connoisseur of retro computing.

The details within the book enabled users to perfect their coding skills in both BASIC and advanced machine code. To this day it remains a highly useful guide for those interested in retro games programming on the classic machine. * * * As the original publisher Melbourne House wrote: Here is the definitive book for the Commodore owner. A complete and comprehensive guide to make you total master of your Commodore 64. Commodore 64 Exposed is an encyclopedia of solutions from Basic programming through to machine language, and includes vital tables of memory locations and system variables. The step-by-step format is designed to ensure that every owner will understand exactly how their Commodore 64 works. Every feature and program variable is carefully explained with the aid of simple demonstration programs that can be entered in minutes. Whether you are a first-time computer user or a serious programmer, if you want to take full advantage of your Commodore 64's impressive capabilities, then this is the book for you. * * * Acorn Books is proud to present its Retro Reproduction Series, a collection of classic computing works from the 1980s and 90s, lovingly reproduced in the 21st century.

In this book you will learn to program a game step by step in Commodore 64 assembly. You will learn to make a big 100 x 100 character multicolor map in CharPad on scroll it on the screen. You will also learn to show sprites, animate characters, play music and sound effects and much more.

First published in 1982, William Tang’s Spectrum Machine Language for the Absolute Beginner is generally considered to be the best introduction to 8-bit machine code programming ever written. With many great game writers crediting this as the book that got them started, there still is no better way to learn the language at the heart of the ZX Spectrum. * * * As the original publisher Melbourne House wrote: If you are frustrated by the limitations of BASIC and want to write faster, more powerful, space-saving programs or subroutines, Spectrum Machine Language for the Absolute Beginner is the book for you. Even with no previous experience of computer languages, you will be able to discover the ease and power of the Spectrum's own language. Each chapter includes specific examples of machine language applications which can be demonstrated and used on your Spectrum as well as a self-test questionnaire. At the end of the book, all this is brought together in an entire machine language program - from design right through to the complete listing of an exciting, original arcade game. * * * Acorn Books is proud to present its Retro Reproduction Series, a collection of classic computing works from the 1980s and 90s, lovingly reproduced in the 21st century.
