Hi Dylan, We have at least half dozen old working ones in our basement! Great fun, especially when we are having a party. I'm still holding out hope for a Rocky & Bullwinkle machine, but they are very very pricey. RIght now the family favorite is probably Cyclone.
The first electronics teacher I had (in High School) taught us debugging techniques by creating several 'circuit' boards (wooden planks) where switches, solenoids and light bulbs were connected up in different ways. Each board had a particular 'bug' (missing connection, miss-wire, short circuit) that we needed to find and fix. This was the reason I got into electronics as a profession. Getting paid to figure out these puzzles and then seeing something work that I fixed- what a deal!
