Thanks for posting this, Dan.
So the blue section in your post is a review copied from the website that you linked us to. (I missed that on the first speed read of your post, but got it on the second, slow pass, with a cup of coffee in hand.
)
The guy who posted the review that you have quoted seemed rather negative. Not sure what he was expecting. It sounds to me like a book I would find useful. The old technology is exactly what I would want to read about. That's the part so many of us on here struggle to master--the old technology.
