What is this computer game called? It's really old.?

There is this really old game I used to play onthe computer, and I think they had it out for the nintendo too. It was sort of like a logic game where you had to figure out how to solve the puzzle with different teeter-totters and pullys and stuff. It was like a teacher or doctor that was like, helping you out. I think it was called something like, Mean Machine or something? I searched for it but couldn't find it. Does anyone have any idea??
