The LE-80M calculator is one of the early calculators manufactured by Canon missing a calculator chip from Texas Instruments. The brain of the LE-80M is a Hitachi HD3553 chip.

There are two other models in the LE-80 family:

LE-80 without the memory
LE-80R with the square-root function

The housing of the LE-80M is very similar to the original LE-80 but got a new battery compartment.

With the LE-81M the Texas Instruments chip was back. This calculator sports both a memory and the square-root function.

Within the later scientific calculator line most products missed the calculator chips developed by Texas Instruments. Browse the Palmtronic F-51 and Palmtronic F-71.

In 1974 Canon introduced with the LD-80 their first pocket calculator with the green VF-Display (Vacuum Fluorescent) and stopped the LE-series.
