Variant of a Model F/AT PC Keyboard

The IBM Personal Computer AT Keyboard was the successor to the IBM PC and PC/XT Keyboards (Model F/XT) as IBM's main PC keyboard and is the last wholly unique Model F design and capacitive buckling springs host introduced. It was released at the same time as its host PC, the IBM Personal Computer AT (PC/AT) in August 1984, which was the final major release of the original IBM PC series. What's now commonly referred to as the "Model F/AT" represented a big step towards the now-standard PC keyboard design with its introduction of the ANSI-style large left shift key, separated numeric keypad and LED lock-lights to the IBM keyboard family. However, it would be quickly supplanted by the IBM Model M Enhanced Keyboard within two years. As the name implies, the F/AT uses the "AT" protocol (IBM scancode set 2) like later PS/2 keyboards. This meant that until the 2010s, F/ATs were considered the most valuable Model F keyboards as were amongst the few Model F variants that were easily adaptable to modern systems.
