Calculators > Specific Collections


APF was an american company manufacturing consumer electronics. I will not repeat the history, as it is documented in many WEB sites, but the interesting thing to note is that the name of the company is based on the initials of the founders: Al and Phil Friedman.
They produced many calculators and here is the list of those that I know.

Note:
Pictures of calculators that I do not own are from Ebay web site, and simply for illustration, to show what the calculator looks like. They are also not in scale from each other.
