The Canon LE-85 uses the TMS0807 calculator chip instead of the TMS0101 used in the earlier LE-83.
From the technology the LE-85 is similar to the Exactra-19
introduced by TI same time.
The
LE-85 and its sibling LE-84 were the last pocket
calculators in Canon’s line using the red LED display. The display of the
pictured calculator was supplied by Rohm of Japan and looks somewhat different to
the known LED-sticks.
The next calculator
generation introduced with the LD-80 the green
VF-Display (Vacuum Fluorescent). Main advantage of this technology was that time
both lower power consumption and cheaper purchase price.
