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.
