Anyone still using the old Nintendo Computrainer?

…if so, what kinds of things are you doing to it? Upgrading? My CT is circa 1994 and appears to be going strong as I just pulled it out of the closet to ride it for the first time in many moons…feels smooth. I used to hurt myself on it severely and am not sure if it is necessary to upgrade it or not. I would also be interested in some favourite workouts on it…thanks,
