A very early counting device, the Salamis Tablet^[1], was discovered on the island of Salamis in 1846. It is believed that the Salamis Tablet was used by the Babylonians to track numbers in their society around 300 B.C. On this board, physical markers(indicators) were placed on the various rows or columns that represented different values. The indicators were not physically attached to the board.
