While it contains recipies, it's not really a recipe book, but a book that discusses the theory of making curry. The recipies are really just worked examples. Similarly, I'm working though Don's book. It's not a collection of recipes on how to combine TTL devices. It's actually a practical course in digital circuit design, with a few notes on which 74 series chips are suitable for given problems. I'm about half way through the book and have learned quite a lot that is directly applicable to cutting-edge FPGA design. I particularly like the ingenious design used for the bit-paired keyboard that doesn't even use a look-up table to generate ASCII codes. Given the same task now, I'd have used an Arduino :)

I recently purchased the "TV Typewriter Cookbook" from eBay. I assume the 2 books are quite different, looking at contents and such. However is there any relationship between them, like do they depend on knowledge from each other? It seems the "TTL Cookbook" teaches more basic stuff. Regards, Vlad.
