Books - Manuals: "Apple II Reference Manual - Preliminary"
Before the "Red Book" was this printed manual with the information needed to get started using the first release of the Apple II.As with the later printed manual, this preliminary manual contained a large amount of very specific and technical information that was provided about hardware, including ROM entry points, and how to modify the computer to your own needs.
