The Optonica line as it was called, consisted of high quality and technically advanced components, that was expanded in 1979, to cover a broader selection of high end equipment. Sharp ventured into the high end stereo market in 1976 with the introduction of high end receivers, amplifiers, speakers, turntables and cassette players. Sharp introduced low-cost microwave ovens affordable for residential use in the late 1970s. One of the company's main inventors of LCD calculators was Tadashi Sasaki. All of these units are considered collectors items on the secondary market. Sharp had a working relationship with Nintendo during the 1980s, and was granted licensing rights for the manufacture and development of the C1 NES TV (1983, later released in North America as the Sharp Nintendo Television), the Twin Famicom (1986), the Sharp Famicom Titler (1989), and the SF-1 SNES TV (1990). Sharp produced the first LCD calculator in 1973. The company was renamed Sharp Corporation in 1970. Also in the same era the company introduced the first microwave oven with a turntable between 19. 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').
