This was the first pocketable calculator priced at less than JP¥100,000 (less than US$300), and turned out to be a popular item. Its first LSI calculator was introduced in 1969. Two years later, in 1966, Sharp introduced its first IC calculator using 145 Mitsubishi Electric-made bipolar ICs, priced at JP¥350,000 (about US$1000). It took Sharp several years to develop the product as they had no experience in making computing devices at the time. In 1964, the company developed the world's first transistor calculator (the Sharp CS-10A), which was priced at JP ¥535,000 (US$1,400). In 1953, Hayakawa Electric started producing the first Japan-made TV sets (the "Sharp TV3-14T").
