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.
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.
