May not answer this directly, but Tim Cranmer invented the Cranmer abacus. The oldest surviving counting board is the Salamis tablet (originally thought to be a gaming board), used by the Babylonians circa 300 B.C., discovered in 1846 on the island of Salamis. The abacus is still used in China and Japan.
