Shoutout to the old Otis relay logic trainers from trade school

We had to wire up a whole floor control circuit on one of those boards, and it took me two days to get it right. Then last year, my company sent me to a class on the new PC-based simulators. I had the same circuit running in about an hour because the software showed me the exact spot where my virtual wire was wrong. It was a huge time save for learning. Anyone else make the switch from the physical trainers to the computer ones?

Remember when the only debugging tool was a sore back from leaning over the board for eight hours. Progress is just the universe giving us the same puzzle but with the answer key printed on the back. I do miss the smell of hot relays and desperation, though.

Oh man, that hits close to home.
