The 6502 integrated circuit is a very popular microprocessor that is currently being used in general-purpose micro computers, video games, and personal computers. Chapter 1discusses the characteristics of the 6502 integrated circuit and the AIM 65 microcomputer. Although the AIM 65, a 6502-based microcomputer manufactured by Rock'tve ll Internat ional, has been used to generate and test the program examples given in this book, most of the programs listed can be used on aH 6502-based micr )computers. However, they may have to be slightly altered to reflect the memory and I/O devices that are wired to your microcomputer.
