i had a binatone pong game that sounds like it was based on this chip. It had a bunch of variants of pong you could play based on moving a couple of physical sliders -- squash (bounced off a wall), football (two bars per player), etc. The crazy thing was that if you turned the sliders just right, you could also play "off menu" games which had combinations of the attributes of the official ganes. I guess this was down to some of the tricks described here. It certainly confused me a lot when I learnt to program: you can't just compose two games together by half-clicking on an option!
