520			_aFirst published in 1985, this user-friendly guide to coding machine language on the Atari 130XE helped many owners of the much-loved home computer achieve programming feats well beyond the limits of BASIC. Based on the MOS Technology 6502 CPU running at 1.79 MHz, the 130XE was one of Atari's famed 8-bit range - in fact the first home computer series to be designed with custom co-processor chips.* * *As the original publisher Melbourne House wrote:Go beyond the limitations of BASIC and write faster, more powerful space-saving programs using this guide compiled exclusively for Atari 130XE users.Atari 130XE Machine Language for the Absolute Beginner offers complete instruction in 6502 machine language. Each chapter includes specific examples of machine language applications which can be demonstrated and used on your own Atari 130XE.Even without any previous experience in computer languages the easy-to-understand 'no jargon' format of this book will make the art of machine la.
