Canon F-62

The Palmtronic F-62 Scientific/Statistical calculator is unique within the products of Canon. The housing looks unknown to us and we are really curious about the source of the calculator.

The backside of the F-62 gives us no further information. We just notice two really big lithium batteries of the CR2430 type. 

Removing the shells of the calculator housing is disappointing, too. No name on the printed circuit board (PCB), an unknown calculator chip manufacturer with missing chip designation.

In a next step we use Mike Sebastian's "Calculator forensics" and notice with the result of 9.0001495952 one sibling in his list: The APF Mark 8601 - probably the successor of the APF Mark 8501 known from the Radio Shack EC-496.

We noticed a very unusual behavior of the Canon F-62 while preforming some calculations with it: 

• The F-62 accepts only 10 digit entries but during 
long divisions it adds a leading "0" as 11^th digit 

• The entries fill the display from the left to the right

Fellow collector, please drop me a line if you know more about the F-62 or the APF Mark 8601.

A similar calculator was introduced with the Palmtronic F-52, don't miss the Canon card F-63 and F-64.
