It took me a couple of decades, but I *FINALLY* built what Pop-Pop was building in the woodchuck hole. Much like his MITS Altair, Teletype, and Ham Radio in the basement with twisted-pair networking up to the ADM-3A terminal in the kitchen, I have finally built the modern equivalent in our house.
Pop-Pop would have truly enjoyed and appreciated this. It is very much a continuation of his work.
