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.

F-62_1.jpg (58246 Byte)The backside of the F-62 gives us no further information. We just notice two really big lithium batteries of the CR2430 type. 

F-62_PCB.jpg (57151 Byte)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 11th 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.
