Abstract
A pre-connected pointing device assembly retrofitable onto the keyboard of an existing computer system includes an analog input unit and a digital input unit physically and electrically interconnected to a data processing unit by flexible bands. The units and flexible bands are adhesively secured to the keyboard. The analog input unit is placed between two of the keys of the keyboard and the digital input unit is placed at the edge of the keypad area, preferably below the space bar. The data processing unit can be configured to fit in a recess at the rear of the keyboard.
