Description
In 1967 Sony Corporation of Japan began to sell commercial electronic calculators under the name SOBAX, or solid state abacus. This is a later Sony “integrated circuit calculator,” the SOBAX ICC-2500, released in the United States in 1969. The calculator carried out routine arithmetic operations and took square roots automatically. Using various memory keys, it could be programmed to perform routine numerical calculations with diverse constants. There are 15 places in the register.
A mark on the right front of the machine reads: SOBAX (/) 2500. A mark on the front left reads: SONY. A mark behind the keyboard reads: SOLID STATE ELECTRONIC CALCULATOR. A mark on the back reads in part: SERIAL NO. 602827.
