The computer is perhaps among the most revolutionary inventions in our history. Its presence infl uences our culture and each of our lives in many ways. Particular prominence belongs to the microcomputer, known as the "personal computer." You might use a personal computer such as the Commodore 64 or Commodore 128 to help manage a small business, to do schoolwork, to plan the home budget, to keep records, to write, or even to play games. Knowledge of computer software applications, however, is not necessarily accompanied by knowledge of the computer hardware and its functions.
Being a machine, the computer can malfunction and break down, just like any other device or appliance you might use. If you've had your computer for a while, and it's beginning to show signs of age and wear, you might have already experienced trips to a computer service center, with their disheartening repair bills. Although you are not a computer technician, and you do not know dc and ac electronics, you do feel you are capable of having more control over the care of your computer-saving yourself time and money.
This book helps you attain that goal. You need no previous experience with computer programming or repair for this book to be useful to you. All you need is a conscientious desire to take better care of your Commodore and to diagnose problems as they emerge.
