The Sanyo ICC-0161 was Sanyo's first so-called "Mini" electronic calculator. It was also Sanyo's first machine to utilize large scale integrated circuit technology, with a four-chip LSI chipset making up the main logic of the machine. Initial production of the ICC-0161 calculator used LSI chips made by General Instrument in the US for Sanyo, as Sanyo did not yet have facilities to fabricate the advance IC's. Usually these chips will have SANYO printed on them, with a smaller General Instrument (GI) logo. Later, Sanyo developed the capability to make the chips themselves under license to General Instrument, and the chips would only have SANYO printed on them. The LSI integrated circuits made it possible to dramatically shrink the physical size of a 16-digit calculator from Sanyo's earlier-generation of small-scale integration desktop calculators such as the ICC-162. Basic four function calculator with fixed decimal settings. AC-power only. Individual gas-discharge seven-segment tube-type display. Note that the most-significant digit of the display on the pictured machine is non-functional.
