IBM Quiet Touch Numeric Keypad
19-key pearl white variant
eg, P/N 84H8537
Key Tronic made 19-key numeric keypad option for an IBM Quiet Touch Keyboard with TrackPoint II. Its design is based on the IBM Numeric Keypad for IBM PS/2 L40SX but in a new cover set designed to match the design of its host keyboard and has no electronics inside. It has a single modular 10P10C port on the back to couple to a host keyboard, which instead acts as the keypad's controller. This variant has a "00" key on the bottom row, a 2-unit high "Tab" key in the bottom-right corner, and a single-unit "Enter" key above it.
