Apple Interfacing for Apple II.

The purpose in writing this book is to introduce you to the signals within the Apple II computer and to show you how these signals can be used to control external devices under the control of BASIC language programs. A general-purpose computer interface breadboard has been developed to speed your circuit design and testing so that you can easily perform the many interesting experiments that are included in the book. By using a design system such as the one
described in this book, you will spend your time concentrating on the ·principles involved, rather than troubleshooting your circuits.
However, you will have the opportunity to build and test many digital circuits, as well as circuits that use digital-to-analog and analogto-digital converters.
We have chosen to use the Apple II computer with 16K of read/write memory, and the Applesoft BASIC interpreter program. This software provides a great deal of flexibility and it is worth having it available when you are using external interface circuits. The Applesoft BASIC interpreter has two general-purpose commands that can be used to transfer information to and from the computer. These instructions are easily mastered, without requiring a detailed
understanding of the 6502 microprocessor integrated circuit (IC) that is used as the "heart" of the Apple II.
