Rudder Pedals?

[Schwack]

I just saw what might be a pair of rudder pedals at Goodwill for $6. They look to be in good shape and the tension is strong. They each have a wire with what looks like a headphone plug, and they each have two grooves on the bottom, so it looks like they are designed to plug into and fit into another unit. I cannot find in the computer section anything that looks like it could be the base unit. Does anyone have any idea if these are for a computer, and what I should be looking for, or if they were just placed in the wrong area?

If they don't have a USB plug on them, forget em.
