It might be possible. Just some quick info I stumbled across with some googling.
It looks like you can buy this keyboard new for $125
here. No info as to what type of keys it has.
Kind of related. This site also sells
replacement keyboards. And they do mention this, "All of the keyboards below with a "T" in the part number (except the CLIKB122TX) are the heavy duty "clickey" Tactile Feedback models you are familiar with, like those on IBM InfoWindow Twinax and Coax Terminals."
