The Canon Palmtronic F-31 is another calculator based on the TMS1000 Microcomputer family. The TMS1045 found inside the F-31 is simlar to the calculator circuit of the TI-2550-III.
Don't miss the Canola L813, Toshiba BC-8111B and BC-8112SL using the same brain without looking like a scientific calculator.
The next steps in the scientific calculator line were the Palmtronic F-41, F-51, and F-61.
The housing of the F-31 was used with the third series of the Palmtronic LD-10M, too.
