About this keyboard type

The 50-key Model Ms ("M50s") were matrix-style keypads intended for IBM Personal System/2 computers running bank teller applications. They first appeared in November 1987 for the IBM 8530-R02, a version of the IBM PS/2 Model 30 intended for such a purpose with IBM 4700 host support. They possessed the same physical layout as the 50-key Model F-based IBM 4704 Model 100 keypads and could come with transparent, functional or alphanumeric legends. These are one of two Model Ms whose internal assembly is based on an older Model F device and thus takes several production values from Model F designs; individual barrels, metal barrel plate, foam padding, and no plastic rivets holding the assembly together. The assembly's previous incarnation was the aforementioned 50-key Model F IBM Model 100s these M50s replaced.
