Anyone remember Lakeside Games "Trac 4"? It was a late 70's early 80's game.
You must match a pattern shown on the tower by filling your tray with 16 cubes. You must complete your tray and switch off the tower before the tower shuts itself off. The tower will shut itself off after going around 12 times.

Must be nearly 30 years since i last saw one, but yes, i remember the game. Never owned one myself but remember playing it. Saw a "Honda" advert on TV tonight, and something about it triggered my memory of the game. Nice to now somebody else remembers it, couldn't find any other links to it at all!
