Anyone else remember Rocky's Boots

Am I the only one that played this game? A quick discussion over at DC brought back memories of Rocky's Boots. Funny thing is the graphics were actually decent for back in the early 80's.

Rocky’s Boots was a visual simulation that made it possible for upper-grade-school students to design simple digital logic circuits, using a joystick to move around circuit symbols on the screen and plug them together. The circuit components were AND gates, OR gates, NOT gates, and flip-flops. The colors orange and white were used to show the logic states ‘1’ and ‘0’ of the components, so that as the circuit operated, the signals could be seen propagating through the circuits, as if the electricity was liquid orange fire flowing through transparent pipes.
