, a physical key that had to be plugged into a computer’s parallel port (LPT1) for the software to function. Often jokingly referred to as "dongles" or "dogs," these devices became a staple of the engineering, CAD, and creative industries, creating a unique and often frustrating subset of computing history known as the "dog driver." 1.
