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.
How do you squeeze a calculator in a 0.15" (4 mm) thin housing? Dismantling the FC-52 reveals an interesting construction based on a very thin plastic frame with even a gap for the conventional Toshiba T3808 single-chip calculator circuit.
