About this keyboard type

The so-called "blue switch" Model F terminal keyboards were a series of five distinct keyboards for originally the IBM 3178 Display Station in Q1 1983 and later for the IBM 3104 Display Terminal. Characterised by their blue switch used for toggling the terminal's display between uppercase + lowercase or uppercase-only display, these Model Fs featured a heavily modified XT-like layout with two or three function banks.
