DATAMATH CALCULATOR MUSEUM
|The Canon F-62 with two really big lithium
coin batteries with the
unusual CR2430 size. Other calculators use the more common
CR2025 type or even the small LR44 batteries.
|The internal construction
of the F-62 gives no sign of Canon as
manufacturer of the calculator.
The calculator chip is easily identified as NEC uPD1856G.
|Even the similar F-52 kept the secret of the manufacturer.
