About this keyboard type
The 102/103-key Model M terminal keyboards were amongst the first introduction of the standard Model M design, released in June 1985 for the IBM 3161 ASCII Display Station. Used on various IBM terminals such as the 3151, 3192, and various InfoWindow display stations, these keyboards heavily resemble PC-compatible IBM Enhanced Keyboards but commonly lack any lock-lights, featured 240-degree pin arranged DIN or modular 8P5C connectors, and have an extra key (102 vs 101 for ANSI, 103 vs 102 for ISO) by splitting the usual numeric keypad + key into two 1-unit keys. Unicomp is still able to produce keyboards to a similar spec.
