A few years ago I took a ton of data books off the hands of a member from a lovely part of Bristol. I am remiss in that I have forgotten his name/ID.
I have found fascination in these books, partly through stirring memories of chips from yesteryear, and partly through the excellent application notes that some of these books contain. I can find almost any data sheet on t'interweb yet nothing comes close to a real book in your hand.
I have had particular pleasure thumbing a copy of Lesea and Zaks 'Microprocessor interfacing techniques', that was amongst the books I acquired. I owned a copy of this book many years ago but lost it following a company collapse. It is really lovely to have a copy again.
Thanks are due to the person who gave me these books, whoever you are
