About this keyboard type

The IBM Model 100 was the first and smallest keyboard for the IBM 4700 Finance Communication System's 4704 terminal introduced in October 1982 and is the second smallest known Model F assembly. Usually featuring 45 transparent keys and 5 hard-set function keys, the Model 100 acted as a sort of macro pad for the system by allowing the user to map functions to those 45 transparent keys and put custom labels underneath them.
