The “Woz Wonderbook” was a compilation of notes from Steve Wozniak’s filing cabinet that served as the first documentation and technical support manual for the Apple II computer (before the more famous “red book” of January 1978). Bill Goldberg, longtime Apple employee, donated his copy of the Wonderbook to the DigiBarn (thanks BIll!). At the time he was at Apple there was only a single copy of this thick binder of photocopied notes, diagrams and such to be found in the Apple library. Bill, being in the technical support role and a natural pack rat, made a copy of the Wonderbook.

David Craig, an expert archiver and scanner of Apple documentation has kindly scanned in, organized and created a wonderful PDF version of the Wonderbook.

    I also love that “The Apple II Circuit Description” is a published book that exists:
