IBM-made 122-key terminal emulator style keyboard intended for use with the IBM 4456 TEMPEST PC III (aka, TPC III or TPC3), a TEMPESTed version of the IBM 3270 Personal Computer. This keyboard is based on the IBM 5271 Personal Computer Converged Keyboard but has a slightly altered layout (the backspace key is now 1-unit and the left shift key is now ANSI-style), a different connector (DE-9 instead of 240-degree 5-pin DIN plug) and internal shielding around its controller electronics. Its 24-key function key bank has "PFxx" nomenclature legends.
