1974 Canon introduced with the Palmtronic LD-80 their first pocket calculator with the
green VF-Display (Vacuum Fluorescent) and stopped the wonderful LE-series
started with the famous LE-10. We remember all the
calculators using the red LED-Displays: LE-80,
LE-80M, LE-80R, LE-81, LE-82
and LE-100 before the LE-83,
LE-84 and LE-85 settled the
design line. Both manufacturing costs and operating time outdated this
technology and we got the new LD-series.
LD-80 used with the TMS0855 a calculator brain similar to the one found in the
rare TI-150. With the basic four
functions, a [%] key and the optional sqr-function it found its way into
most other calculators of the Palmtronic LD series.
The LD-80 used an unique design and looks more or less like some Sharp calculators. The later LD-81 defined with its blue, yellow and black keys the appearance of the „Palmtronic“ calculators and this style was kept even with some calculators using the LC-Display (Liquid Crystal) like the LC-8M.
Shortly after the introduction of the LD-80 a more or less identical calculator called Panther D appeared on the market.
Don't miss the Palmtronic 8 mini introduced about 1975.
