Canon card F-63 Scientific/Statistical calculator was introduced together with
the F-72 in 1980. Both calculators sport a total of 59 keys compared with the 40
to 45 keys of similar products.
Dismantling the Canon card F-63 is time consuming, we noticed more than 20 tiny screws.
This Canon card F-63 was manufactured end of 1980 and is centered around a Toshiba T3801S single-chip calculator circuit.
Mike Sebastian's "Calculator forensics" reveals for the Toshiba T3801S chip a fairly good result of 9.0000278593, known from later calculators, e.g. the Toshiba SLC-8310, TI-35 Solar and even the first generation of the TI-30 Galaxy introduced in 1984.
