Both the Chinese and Japanese abaci were made with wooden frames. But beginning with the Chinese version, we have a proper frame. The old versions were made by carving sections on wood. FrameĪ frame is the outer body of the counting device that holds together the other parts, such as the beads and the rods. In this section, I will tell you about its different parts. While the earliest models were counting boards, the modern models are counting frames.
