Sony Sobax ICC-500 Electronic Calculator

Description
By the early 1960s, Sony Corporation had gained an international reputation for such consumer electronics products as a pocket transistor radio and a transistorized television. It exhibited a prototype desktop electronic calculator in 1964. In 1967, it released the SOBAX, or solid state abacus. It was called an "ICC" or integrated circuit calculator. By 1968, the machine sold in the United States for $1,250.
The non-printing, four-function desktop electronic calculator has an array of nine digit keys at the center front. Zero and decimal point keys are below these. Immediately to the right are cancel, subtraction, and addition keys. Right of these keys are memory clear, memory input, and total keys, as well as a round-off switch.
Immediately to the left of the digit keys are division, multiplication, and result keys. Left of these are repeat and memory out keys. Still further left are the on/off switch and the clear key. Behind is a fourteen-digit display window. A decimal point lever is below the result display, and a minus lamp is at the far left. The case includes a plastic handle at the top. A cord extends from the back and can be wound around protruding “cord anchors” for storage.
A mark on the left front of the machine reads: SOBAX. A tag at the top reads: SONY.
