That would have been a good while ago. You didn't build digital stuff out of TTL on breadboards? Now that I'm typing this, I am getting a hint from the parenthetical "(or relay (or tube))" :)

edit: I was personally an innovator of the "WAS" gate. They're made of smoke.

There were American SN7400s in 1974 of course, but they were expensive compared to single transistors. I also remember the Finnish Parliament voting machine, made with transistors and relays around 1968. It was huge incomprehensible mess on hand-wired breadboards. It was easier to make totally new one with microprocessors and printed circuits.

What was a "WAS" gate? Google does not seem helpful here.

I'm going to assume that the WAS gate was a NAND...until the smoke got let out.
