70s TTL had taken over the world because it reduced the issues of
fan-in, fan-out and rise-times. But I still have one of my first
books on the topic - "Logic Design With Integrated Circuits" by
William E Wickes published by John Wiley and Sons 1968. It is still
the first thing I reach for when I want to do minimization -
something of a lost art given the size of CPLDs and FPGAs.

pretty much own this market and you don't have to put it together.
I don't know if there is enough of an increase in the number of
people interested in electronics to drive a kit based test equipment
market or not. There is so much used equipment on eBay.
