The Unicomp On-The-Stick was the continuation of Model M13 production after Lexmark finished producing Model M keyboards. The chassis is based on the Lexmark-produced moulds, however, Unicomp replaced TrackPoint II with their own force-sensitive resistor based Pointing Stick. Other changes included improved tactile mouse buttons and the removal of the PS/2 mouse pass-through port. The On-The-Stick exited production around 2009.
