Canon
entered with the Palmtronic LC already in 1976 the market of LCD calculators and
was about 6 month ahead the first Texas Instruments TI-1750.
Compared
with the LC-2 introduced early in 1977 this later LC-3
hosts a NEC uPD888G single-chip calculator circuit instead the uPD877G but makes
use of an identical printed circuit board (PCB).
In a later redesign the LC-display was changed from the yellow polarization foil
to the usual grey type. Don't miss the second LC-1, LC-2,
LC-4,
LC-5,
LC-6
and
a later LS-6.
