Description:
Older Thinkpad keyboards have full size keys that feel much better than the “chicklet” keys on modern laptops. A nice feature of these keyboards is the trackpoint eraser head that takes a lot less space than a touchpad. Newer Thinkpad keyboards have a built in circuit that converts the trackpoint resistive strain gauges to PS/2 but older Thinkpads, like the 380ED, rely on circuitry external to the keyboard to do the conversion.
