The Unicomp EnduraPro is a compact-profile full-size Model M featuring the thinnest side bezels ever put to a Model M design. It was introduced around the turn of the Millenium and eventually gave rise to the SpaceSaver/Ultra Classic family of keyboards that lacked integrated pointing sticks. EnduraPros are produced using the same moulds formerly used to make IBM 5576-C01 keyboards in the '90s. Unlike the 5576-C01, these use Unicomp's unique FSR pointing sticks instead of IBM TrackPoint II.
