History

The earliest computer-related usage for a stylus was in 1643 with Pascal's calculator. The device had rotary dials that rotated in accordance with the selected numbers; with gears, drums, and clever engineering, it was capable of addition, subtraction, multiplication and division (using 9's constant). A stylus was used to turn the dials.
