I used to own one of these:

The movement of the chair acted as the D-Pad. You pressed your legs against the stationary foot pads and the chair would rock back with resistance, somewhat like a rowing machine. Though I think you pulled in with your arms and abs to advance forward. I remember it making a satisfying click sound when you activated a D-Pad direction button. The remaining buttons were on the stationary arms.
I had the SNES version and the manual recommend racing games like Top Gear.
It was almost impossible to control games using the device. Aside from the fact that you could not react quickly, you quickly got exhausted trying even when you cranked down the resistance level.
I've never seen one show up on eBay or on this forum before, hence this post. Does anyone have one in their collection? My family got rid of ours around 2000. I think we tried selling it in yardsales a few times. After no buyers, we just dragged it out to the trash. It was using up a ton of space and this was well before the age of retrocollecting.
