More about this type of keyboard...
The Model M terminal keyboards were the first introduction of the standard Model M design. Used on various IBM terminals such as the 3151, 3161, 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.
