If you are reading this book, you have either bought a computer, will buy one, or are at least considering the idea. Its purpose is to provide you with enough information about the Commodore 64 computer to use it well. You will learn what it is, where it came from, and what it can and cannot do for you.

First, and to the point, this book is only about the Commodore 64 and other computers in the same family (a portable and a classroom version). Aside from certain basic ideas common to most computers and references to other computers manufactured by Commodore—the VIC-20 in particular—you'll learn little or nothing about how to use an Apple, or TRS-80, or Atari, or any other personal computer.
