Oldest Portable Clockwork Computer Even Older

The Greek Antikythera clockwork computer that modeled the motion of planets and predicted the times of Olympic games may be older than thought. New Scientist reports on how the device may be as old as 200 BC because it includes references to minor games that would not have been included on the calendar during the Roman period. I think it´s a wonderful piece of technology and another indication of how much knowledge may have been lost from that period before rediscovered in the latter half of the last millennium.
