More about this type of keyboard...
The 102-key Model M terminal keyboards were the first introduction of the standard Model M design. Used on various IBM terminals such as the IBM 3151 and 3161 ASCII Display Station and IBM 3471 and 3472 InfoWindow Display Station, these keyboards were the first taste of what would become the IBM Enhanced Keyboard. Common features included lack of any lock-lights, 240-degree DIN or RJ-45 connectors, and a modified ANSI-like design with the 102nd key found on the numeric keypad.
