The dashboard of a car takes its name from the eponymous piece of wood on a stagecoach; the same concept eventually gave its name to a software design pattern showing a row of data readouts.
But what data did the first dashboard to contain any instruments show? While I'm assuming it'd be a motorcar dashboard, I'm open to suggestions of other dashboard form factors such as a ship's helm, as long as they came first and fit the mold of a board with instruments on it.
