More on this type of keyboard...
The IBM System/23 Datamaster Floortop Keyboard was amongst the first buckling spring keyboards, released by IBM in July 1981 alongside the Desktop variant. The Floortop variant was a discreet keyboard module for the IBM 5324 unlike the integrated 5322's Desktop variant. Its physical assembly would be reused only a month later for the IBM 5150 Personal Computer's keyboard (the Model F/XT). The System/23 didn't sell as well as the IBM PC, thus these are quite rare and its host computer is very expensive.
