Old computer book found (fascinating reading/photos):Design of Real Time Computer Systems (J.Martin 1967)

Hi Just taught I would let you know I am reading this : Design of Real Time Computer Systems (1967 J.Martin)found in a thrift store for $2 and it fascinating - at least for me... Just facinated by the photos and the concepts in there...I was 3 at that time (1967) never used computers before I was about 15-16 (model III I am still hunting for one...) Will just have to scan some of these photos for my vintage computer collection web site. I don't have machines from that era but some of these pics are just great!!! Since I have so much space left in my basement (already use 2/3 - I love my wife...) I seem to have now made the very reasonnable decision to extended my vintage computer collection to old books, magazines and manuals...I might have develloped some kind of mental illeness now, I recently mentionned "need more space for computer collection" as a reason to my wife to justify getting a larger house...
