> Then around 1976 came “David,” using the Z80 microprocessor, oriented towards team play (the Big Player making the big bets) with hand keyboards operated through holes in pockets and transmitters to signal the Big Player. Later came “Thor,” a computer to track the shuffling (and possible clumping) of multiple decks. One of his inventions involved networking players together with fine wires about 3 feet long. Then there were “Magic Shoes” in which 12 batteries, computer, and all were hidden in “Frankenstein” shoes. Later still there was “Narnia, the sequencing computer.”
The inventor Keith Taft talks about it in more detail in an interview here: https://www.lasvegasadvisor.com/gambling-with-an-edge/interv...
(Another famous '70s card counter, Ken Uston https://en.wikipedia.org/wiki/Ken_Uston ended up writing one of the very earliest video game guides, Mastering Pac-Man (it came out in 1981, the same year as Tom Hirschfeld's https://en.wikipedia.org/wiki/How_to_Master_the_Video_Games .) Apparently one of its readers https://en.wikipedia.org/wiki/Semyon_Dukach discovered Uston's blackjack books as a result, got into blackjack and so ended up on the later, late-'70s-to-early-2000s MIT Blackjack Team led by J.P. Massar .)
The wide interest in things that Shannon held from weird gadgets to possibly the most famous Masters thesis dissertation, Shannon has me in awe and respect. Had he been a good storyteller, I suspect, people would have been as familiar with his name as Feynman.
Here’s an interview with him from a few years ago.
