Our annual Bazaar was held today with all the leftover stuff now at my house ... briefly! In searching through the stuff this afternoon, I found several boards that I couldn't identify. One is labeled "FlipFlop" and the other "Inverter". I put up a picture of both sides of the FlipFlop at: http://www.rain.org/~marvin/flipflop.jpg While not obvious from the photo, it does look like the board has gold plated traces. Does anyone know what these things might have been a part of?
