The Palmtronic F-71 is another calculator manufactured by Canon missing a calculator chip from Texas Instruments. The brain of the F-71 is a Hitachi HD36140/HD36141 chipset. Don't miss the first TI-less calculator sold by Canon, the LE-80M.
The other calculators in the early scientific line are the less powerful F-31, F-41, F-51, and F-61.
In 1980 Canon introduced with the F-72 a foldable scientific calculator with lots of functions.
