Back in 1966, before personal computers and dating aps, I used ibm punch cards to join Operation Match which was a computer program run by U C Berkeley students for free with the objective oh matching up people for dates. It found me my first wife! I wonder if that was the first such program and if the founder went on to be a millionaire.
I did exactly the same thing. It was 1966 at college in Billings, Montana. Yep IBM punch cards were used, but I think we just filled out a paper form, and some tech guy probably transferred that to cards. Everyone lined up in correct order. Men behind the stage on one side, and Women on the other side. A gate keeper guy would tell us when to go out so you and your date entered the stage and met for the first time in front of a dance floor filled with students, probably the ones that came out before us. Students were talking about the big dance for weeks before and days after.
My date was very nice, and of course we talked about about the information we filled out on the forms, and on paper we did match big time, but that was my last year, hers too, and we were both on our ways to start careers.
I played the guitar back then and sang in front of very large groups a few times, and she was a musician and singer also. During the spring we had a big outdoor hootenanny thing, and I was asked to do a couple of numbers. This was the last time I saw her. She was in one of those big musical groups like the Mommas and the Poppas, maybe 10 members in all that were fashionable back in the 60s, and they sounded to me as good as any group that became ultra popular and recorded back then near the end of the folk era. I believe they called themselves The Honeywind Singers. Me? I was JustDave.
Her group came out right before me, and were still hanging out at the back of the stage as I played, and I heard her cheering and shouting at me to play another. Never saw her again after that. I guess it wasn't meant to be. I didn't find my real match until 10 years later.
