I am a beginner and i am in a search of a clear, and detailed book of programming 6502. And i am focusing on an Programming the 6502 by Radnay Zaks (4th edition) 1983. I've looked through most of the old Atari programming books including 6502 and most of them mixed information with BASIC or too simple and very thin. This book is stuffed with many real code snippets with explanation.
