KB 5191 Keyboard

The Leading Edge KB‐5191 keyboard was included in‐box with the D2 Plus computer. The keyboard was a 101‐key ANSI mechanical keyboard with subtle "clickyness" sporting white Futaba PCB mounted key switches, though KB‐5191 keyboards could be equipped with other key switches. Measuring 19" by 7", the keyboard was a standard ANSI layout full‐sized keyboard with dedicated cursor keys and 10‐key number pad. The keyboard also includes four indicator LEDs including Num Lock, Caps Lock, Scroll Lock, and On Line indicators. When paired with the D2 Plus computer, the On Line indicator is always on when plugged in and the computer powered on.

The keyboard interfaced with its computer via a 5‐pin AT plug. A keen observer may notice that the Leading Edge KB‐5191 is in‐fact a rebranded Chicony KB‐5191. The case of the keyboard indicates that a speaker could be equipped inside of the keyboard, though Leading Edge branded keyboards did not opt to include speakers. On the bottom of the keyboard are two two‐position flip‐out stands that elevate the back of the keyboard or lay it flat per user preference.

Back to the top of the keyboard, the ABS laser etched keycaps are populated on the keyboard with a two‐toned layout with most of the non‐alphanumeric keys being a light grey color and the alphanumeric keys colored in an eggshell white.
