Apple II Reference Manual was for the Apple II and the Apple II Plus. Like the Apple itself, the book is a tool. As with all tools, you should know a little about it before you start to use it. This book 'will not teach you how to program. It is a book of facts, not methods. If you have just unpacked your Apple, or you do not know how to program in any of the languages available for it, then before you continue with this book, read one of the other manuals accompanying
your Apple. Depending upon which variety of Apple you have purchased, you should have received one of the following:
Apple II BASIC Programming Manual (part number A2L0005)
The Applesoft Tutorial (part number A2L0018)
These are tutorial manuals for versions of the BASIC language available on the Apple. They also include complete instructions on setting up your Apple. The Bibliography at the end of this manual lists other books which may interest you. There are a few different varieties of Apples, and this manual applies to all of them. It is possible that some of the features noted in this manual will not be available on your particular Apple. In places where this manual mentions features which are not universal to all Apples, it will use a footnote to warn you of these differences. This manual describes the Apple II computer and its parts and procedures. There are sections on the System Monitor, the input/output devices and their operation, the internal organization of memory and input/output devices, and the actual electronic design of the Apple itself.
