FC-52_Back.jpg (180312 Byte)This Canon FC-52 was probably introduced together with the FC-42 and started with its "sibbling" Toshiba LC-838 a long line of Metric Converter calculators based on Integrated Circuits (IC's) developed by Toshiba. Canon introduced already in 1974 with the FC-80 their first metric conversion product with a LED display based on a calculator chip developed by Hitachi.
