The Philips Semiconductors TPM754 is a small package, low cost, ROM-coded 80C51 with IBM’s TrackPoint pointing algorithms and control code. TrackPoint is the result of years of human factors research and innovation at IBM. The result is a “velocity sensitive” pointing solution more efficient and easier to use than “position sensitive” devices such as the mouse, the trackball, or the touchpad.
