The Canon card F-42 compares with other scientific calculators like the Texas Instruments TI-20 or TI-25. The later F-58 added statistical functions, the F-55S uses a much smaller housing.
Even
the inside construction of the F-42 is not too exciting, it is very similar to
the Toshiba SLC-8280. We noticed the
Toshiba T3941 calculator IC already in the Radio Shack EC-476.
The F-42 was replaced with the F-44 sporting an unusual
housing. Don't miss the early F-41 sporting still a green
VF-Display and the F-32 sporting a rather unique feature
set.
