The
Canon LE-84 uses the TMS0801 calculator chip instead of
the TMS0101 used in the earlier LE-83.
From the technology the LE-84 is similar to the TI-1500
introduced by TI same time.
The LE-84 and its sibling LE-85 were
the last pocket calculators in Canon’s line using the red LED display. The
display of the pictured calculator was manufactured by Antex and provided by Amcon, Canon's subsidiary situated in
Silicon Valley, California.
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.
