I am trying to find a flight yoke for Mac that is probably no longer produced. I think it was sold by Kensington or Gravis many years ago (early to mid 1990s), and it was called MouseYoke, or something like that. It is a simple plastic box with an aircraft flight yoke sticking out of it. One straps the mouse onto the box and the yoke axle rolls-rotates the mouse ball to simulate flight controls. Does anyone remember this item? Know of where I might purchase one? Thanks.
