I've got the book on my desk right now :-) It's a bit of an unusual book because it is full of technical details but it also has a fair bit of sociological content like "the construction of technical facts", "technological determinism", and "sociology of technological knowledge". This is in contrast to, say, "Minuteman: A Technical History", which is strictly facts and details. They are both good books, but it is interesting how they have completely different styles and focuses.
