LE-84_PCB.jpg (46865 Byte)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.

LE-84_DISP.jpg (20202 Byte)The LE-84 and its sibbling LE-85 were the last pocket calculators in Canonís line using the red LED display. The display of the pictured calculator was manufactured by Antex and provided by Amcon, Canon's subsidary 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.
