Sony Sobax ICC-88 Portable Calculator


Sony Sobax ICC-88, Circa Fall, 1971

The Sony ICC-88 is unusual in that it represented the first electronic calculator made by Sony that utilized a US-made calculator chip-set for its main logic. The machine utilized a version of American MOS/LSI chip maker Electronics Arrays' six-chip S-100 chip-set. This chip-set, introduced by Electronic Arrays in November of 1970, set a new low-price benchmark for full calculator functionality in a MOS/LSI chip-set, making it a very popular chip-set to serve as the brains for calculators from quiet a number of manufactures. Companies including Lago Calc, International Calculating Machines (ICM), Micro Instrumentation and Telemetry Systems (MITS), Caltype(A division of Transitron Co.), Rex Rotary, and Walther, used the chip-set in their calculators. The ICC-88 was introduced to the market in September of 1971, at a time when competition in the portable electronic calculator marketplace was really starting to heat up.

The Sobax ICC-88 is a basic four function portable office calculator, with eight digit seven-segment gas-discharge display, and a numeric capacity of 16 digits, using a special key to toggle the display between the upper digits and lower eight digits on the display register. The machine has a built-in Nickel-Cadmium battery pack, which is charged by placing the calculator into a "docking-station" style charger. The calculator can be operated while in the charging station, or away from the charging station on battery power. The ICC-88 is the only battery-powered calculator known to have been made using the Electronic Arrays S-100 chip-set.
