More on this type of keyboard...
The terminal variant of Model M2 was exclusively designed and released for the IBM 3153 InfoWindow II Color ASCII Display Station. The terminal M2s were functionally identical to the standard Selectric Touch M2s, except they possess a modular 6P5C ("RJ-25"-like) connector instead of PS/2. These keyboards were produced in two variations; PC-style featuring standard Enhanced Keyboard-like legends and ASCII-style featuring many terminal-centric legends.
