LE-82_PCB.jpg (73955 Byte)The Canon LE-82 uses the housing of the LE-80R but replaced the square-root functions with a [%]-key.

All together we identify 4 different calculators with similar features:

LE-80 4-function calculator
LE-80M with an additional memory
LE-80R square-root function
LE-82 percent calculations

From the technology the LE-82 is similar to the SR-10 introduced by TI few months earlier. Another calculator using the TMS0128 single-chip calculator circuit could be found with the JCE Percent.

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