Variant of a Model M3 Numeric Keypad

The Model M3 numeric keypad was an optional attachment for the IBM Personal System/2 L40SX laptop. It was notable for being the first individually-distinct device with IBM's buckling sleeves switches. The keypad also sports a pass-through socket for a PS/2 compatible mouse.
