The
Canon LE-80 was the successor of the Canon LE-10 and
marked with the TMS0101 Canon's first use
of a single-chip calculator circuit manufactured by Texas
Instruments.
The TMS0101 "calculator-on-a-chip" was an MOS integrated circuit announced
by TI in September 17, 1971. Read the original press release here.
The LE-80 still uses an analogue battery meter to give you the remaining operation
time of the rechargeable battery pack.
Later LE-80 models added either the square-root function (LE-80R) or a memory (LE-80M). the LE-82 fits into this line and added a percentage key.
With the LE-81 Canon introduced a very odd calculator.
In 1974 Canon introduced with the LD-80 their first pocket calculator with the green VF-Display (Vacuum Fluorescent) and stopped the LE-series.
