Accession Number: 1994.14.6
Description: Osaka-style abacus is made of wood and has 15 columns of wooden beads, with 1 bead above the horizontal bar and 4 below. There are 4 smooth metal pinheads that serve as markers along the bar and another 4 markers along the bottom edge of the frame to facilitate use by blind individuals. The back of the abacus is enclosed and has a red felt backing on top to keep the beads from slipping out of place. The felt backing was added later at APH, when the company was researching adaptations of the abacus for use by blind people.
