I had one of those, and the baseball version.
The football was useless. When you threw the switch, the effect was akin to disturbing an anthill-- complete bedlam.
The baseball was actually quite playable, as the baserunnners ran around a track, and the pitching and batting was done with mechanical controls... We got the idea to integrate our baseball card collections into the game, to indicate 'who' was pitching or up to bat, or who was going to be 'brought in' to pitch relief. It was quite entertaining for a good little while.
