The Apple II Circuit Description. (book reviews) Stephen Arrants.

Inside the Apple

For the hardcore hackers and hobbyists, a new book has hit the racks that may be just what you are looking for. The Apple II Circuit Description by Winton Gayler from Howard Sams is a large book stuffed with all sorts of hardware information on Apples from Rev. 0 to RFI Rev. D. Although the IIe is not covered, this is still a very valuable book. It is tough, thorough, and labyrinthine.

Six chapters examine every bit of the Apple circuitry. You get information on the 6502, on I/O, video display, and timing. Chock full of diagrams and schematics, this books makes a good addition to your library.

One surprise is that all the schematics and diagrams are readable. I am used to cramped little sketches that resemble bad road maps. Mr. Gayler did a monumental job in writing the book. It is well-organized and well-planned.

Apple II Circuit Design isn't for everybody. You do need some prior knowledge of electronics to understand most of the concepts. But for the serious hacker and hobbyist, as well as anyone involved in repairing Apples, this may be one of the most important and informative books you will own.
