More on this type of keyboard...
The 122-key Model F Converged Keyboard was an expanded and prevalent version of the 104-key Model F Converged Keyboards. A sibling of the 127-key 4980 Display Station Typewriter Keyboard, the "F122" could be considered a convenient combination of the "F104" and the 24/25-key Model F keypad that was designed to operate alongside them. The first "F122" to market was the IBM 5271's Converged Keyboard for the IBM 3270 Personal Computer announced in October 1983 and available from Q1 1984, an IBM Personal Computer (5160 PC/XT based) with additional hardware and software to emulate an IBM 3270 terminal. As such, the "F127" (which was announced and released in October 1983) technically beat the "F122" to market. By March 1984, the "F122" was adopted for IBM's then-new generation of lower-cost terminals - the 3179 and 3180 series. The IBM 3179 Model 1 Color Display Station was a low-price but plug-compatible replacement for the IBM 3279 Color Display Station Models S2A and S2B. The IBM 3180 Display Station was a monochrome counterpart to 3179 and was available in a 3270-compatible Model 1 and 5250-compatible Model 2. The 3180-1 was designed to provide IBM 3278 Model 2 through 5 Display Station functionality, and the 3180-2 provided 5251 Model 11 Display Station functionality.
Besides its sheer size (for which this keyboard earned the modern nickname "battleship" or "battleship-sized" keyboard), the "F122" is recognisable for its 24-key program function key bank inherited from the "F104". Those keys will generally have a "PFxx" nomenclature on 3270-family keyboards and "Cmdxx" nomenclature on 5250-family keyboards, with some isolated examples sporting simply "Fxx". The "F122" also retained the left-hand side 10-key function key bank similar to previous IBM 3270 keyboard designs such as the 327X-75 type and 327X-87 type Model B keyboards but with 2 extra keys. "F122s" had two-setting riser feet that were accessible by pushing large buttons on the keyboard's sides, allowing users a choice of 6-degree, 12-degree or 18-degree typing angle. Unlike the "F104" however, most "F122s" used 240-degree 5-pin DIN plugs on their coiled cables. 3270 PC, 3179-1 and 3179-G "F122s" generally have an 8-position DIP switch bank present, whilst 3180-1 and 3180-2 keyboards lack them. Besides the "F127", two distinct variants in utility and features exist - the IBM 3205 Color Display Console Keyboard (3270-family operator console version of "F122") and IBM TPC Keyboard III (TEMPESTed version of the IBM 5271's Converged Keyboard).
