Most of the trouble-shooting techniques also apply to cars and computers. It's incredible how large a chunk of this manual is totally non-specific to Atari stuff but just general solid information on the technology used in those days and how to maintain it and repair it.

It says in the preface that 'the book' will not turn you into a technician but I've seen some 'technician course materials' that couldn't hold a candle to this one publication.

Very nice to see this preserved.
