Does anybody remember something like this: a wheeled toy that I vaguely recall had stylings something like a tank or an APC or something - or maybe one of those weird vehicles from Damnation Alley[1] - but with a bunch of buttons on top with numbers and directional arrows. You could "program" the thing to roam around on its own by pushing a sequence of directional arrows and numbers. It was something like "Go forward 5 units, turn left, go 4 units", etc. I don't even know now what distance units it used, or if the speed was programmable. Once you programmed it there was a "Go" button that would send it off on its little adventure crawling around the living room (and promptly getting stuck under the TV stand or something, but that's neither here nor there).
