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 original design using a huge calculator chip in a
42-pin plastic housing from Hitachi this LC-2 looks inside more common. Other
changes were the simpler connection between the LC-display with the printed
circuit board (PCB) and avoiding the expensive DC/DC-converter to supply the
calculator electronics. The LC-3 introduced just a few
month later uses an identical PCB but hosts a different calculator chip.
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-3, LC-4, LC-5, LC-6 and a later LS-6. Don't miss the Olympia HIT 2000 sporting the NEC uPD877G single-chip calculator circuit, too.
