In 1964, Sharp developed the world's first transistor calculator, which was priced at Â¥ 535,000 (US$1,400). It took Sharp several years to develop the product as they had no experience in making computing devices at the time. Two years later, in 1966, Sharp introduced its first IC calculator using 145 Mitsubishi-made bipolar ICs, priced at Â¥350,000 (about US$1000). Its first LSI calculator was introduced in 1969. This was the first pocketable calculator priced at less than Â¥100,000 (less than US$300), and turned out to be a popular item.
