1970’s wearable Blackjack computer

The Science Channel ran a BBC show called Making Millions the Easy Way, it was mostly about ways people have fleeced the casinos for millions of bucks using math, mechanics and group play. The MIT story was in there, but one thing I couldn’t find any information on was the wearable Blackjack computers that Keith and Marty Taft made. Read the transcript here, it’s amazing. For a mid-1970’s computer it was extremely advanced (it even used LEDs in the eye glasses). I’m thinking of making one and having an “open class” Blackjack game night at my house where everyone is encouraged to “play” any way they wish. Best hacker wins.
