I thought about a game I've not thought about in ages yesterday, called Robot Odyssey. It was a game I had for my Tandy 1000 EX made by the Learning Company. It was a very involved puzzle game where the central theme was circuit logic. You had three (later four) robots (moving boxes) that you wired to do certain things in the game, like retrive objects or push buttons to open doors. I played the game through a couple of times in junior high and high school, and so learning a bunch of basic circuit logic stuff. To the point that when I got to electronics class my junior year at Gustavus, I already knew the basic symbols of circuit logic and the basics of how to use them.
Some links for Robot Odyssey, past and present:
I recently started to get enough furniture in the basement that I can start to set up some of my vintage computers. When I've set up the Tandy, I will see about getting some screen shots of Robot Odyssey.
