History – The Otis Talking Elevator

Compudigital developed the first talking elevator system and installed it in San Francisco in the late 1980s. The product called the DT8100 “Digitalker” was created by Compudigital and used by Otis to let people know that the elevator was “Going Up”, “Going down”, “Please Exit” and other messages. Later, Country Coach in Oregon used the DT8100 to make their motorhomes also talk. The system monitored tank levels, speed, and other functions to let the driver know that status of systems within the Coach.
