As quite a few people are aware, I tend to *really* like documentation and books. Today was a good day for that as I acquired part of the library from someone who had died a few years ago and was into computers. The computer related books ranged from the 50's to the early 80's. A couple of books I had not seen but look to be very interesting are: The Computer from Pascal to von Neumann - Goldstine The Analytical Engine - Bernstein Sequential Machine: Selected Papers - Moore There were quite a few books on software design, digital hardware design, analog and hybrid computer design, compter logical design, operating systems (including Tanenbaum), etc. This is enough to keep me busy for a while checking them out :). Unfortunately, an H-89 had already been recycled but there is still the possibility that the manuals, etc. are still around. After I cull out the books I want, I'll list them on the Computer Marketplace.
