Happy to help with this anytime. Boy, those were the days. All those 1’s and 0’s moved pretty slowly, and you could do just about anything with a wire wrap tool, a soldering iron, and a 10Mhz scope. Sheesh! Which reminds me of a bit of trivia: John wanted sparks to come out of the “control panels” that were installed in the outer walls of the set as WOPR nearly started WW3. I mentioned to John that this was highly unlikely, and very nearly impossible – maybe he should not do this. But, he was adamant. So, we connected 110VAC to the positive and negative pins of some IC’s, and showed John what that looked like. He thought that was great, and that is what made the sparks in those panels near the end of the big missile sequence.
Stay well,
