LE-80R_BACK.jpg (365116 Byte)The Canon LE-80R is one of the successors of the LE-10 calculator introduced one year earlier. 

There are two more members in the LE-80 family:

LE-80 without the square-root function
LE-80M with an additional memory

The analogue battery meter introduced with the LE-10 gives you still the remaining operation time of calculator. 

LE-80R_PCB.jpg (74496 Byte)Dismantling this Canon LE-80R manufactured in October 1973 reveals a printed circuit board (PCB) more or less identical with the LE-80. Main difference is the calculator circuit, we located the TMS0126 instead the TMS0101

LE-80R_IC.jpg (121791 Byte)The TMS0126 "calculator-on-a-chip" is similar to the TMS0120 developed for the SR-10 and introduced only a few months earlier. Don't miss the Casio ROOT-8S sporting the TMS0126, too.

The housing of the LE-80R calculator was used with the original LE-80 and the later LE-82.

The next pocket calculators in Canon's line were the LE-81, LE-83, LE-84 and LE-85.

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