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 chipset
for its main logic. The machine utilized a version of American
MOS/LSI chipmaker Electronics Arrays' six-chip S-100 chipset.
This chipset, introduced
by Electronic Arrays in November of 1970, set
a new low-price benchmark for full calculator functionality
in a MOS/LSI chipset, making it a very popular chipset to serve as the brains
for calculators from quiet a number of manufactures. Companies including
Lago Calc, International Calculating Machinees (ICM), Micro Instrumentation
and Telemetery Systems (MITS), Caltype(A division of Transitron Co.),
Rex Rotary, and Walther, used the chipset 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 chipset.
