Commodore computers are versatile machines that represent a landmark in the era of personal computers. The use of large-scale integrated (LSI) circuits in these computers enabled millions of people to purchase Commodore computers as their first home computer. The purpose of this book is to show you how to build electronic projects that will enhance your computer. But more than this, the information can provide a foundation upon which you can build. Perhaps this book will provide the spark to ignite your own creativity. Many projects lie on the frontiers of technology. The projects represent a starting point for the basic tools with which you can explore on your own, and perhaps make a contribution to emerging technologies.
