 IBM's keyboards were always built by Lexmark. Recently (a few years ago),
 Lexmark spun off their keyboard operation, which was swalllowed up by
 Unicomp. This keyboard was built before IBM spun off Lexmark, which means
 it was built by IBM.

 The mechanism in IBM keyboards is called a "buckling spring mechanism".

I've two RT keyboards. One is buckling spring and the other has quiet keys
and seems like a cheaper version.
