The 6502 integrated circuit is a very popular microprocessor that is
currently being used in general-purpose microcomputers, video games, and
personal computers. Chapter 1 discusses the characteristics of the 6502
integrated circuit and the AIM 65 microcomputer.
Although the AIM 65, a 6502-based microcomputer manufactured by Rockwell
International, has been used to generate and test the program examples
given in this book, most of the programs listed can be used on all 6502-based
micro-computers. However, they may have to be slightly altered to reflect
the memory and I/O devices that are wired to your microcomputer.
Chapters 2 and 3 discuss subroutines and present descriptions of the
instructions that the 6502 microprocessor can execute. Then, Chapters 4
through 6 present techniques needed to process lists and tables, perform
mathematical operations, and convert data. Finally, a description of ways
to transfer information between the microprocessor and the input/output
devices by using the 6502 instructions is given in Chapters 7 through 9.
