Depending on your definition of "computer", there is evidence of a one 
of a kind "Roman" device that was capable of predicting eclipses, and 
timing the correct date to start the Olympic games, among other 
features. In other words, an electronic calender. But, at that time, 
such things where nearly impossible to replicate, so when the ship it 
was one sank... Arguably, its gearing system had to have some sort of 
"algorithm".
