1982's IBM Electronic Typewriter Models 65, 85 and 95 briefly brought capacitive buckling spring keyboard assemblies to the typewriter market. They're essentially an intermediary step between the Selectric typewriter family and Model M-based Actionwriter/Wheelwriter/Quietwriter family, and are far less common than both. They are also amongst the smallest Model Fs made and use plastic rivets to hold their keyboard assembly together much like Model Ms.
