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

LC-1_PCB.jpg (59408 Byte)The internal construction of the Palmtronic LC uses a huge calculator chip in a 42-pin plastic housing from Hitachi. The remaining electronic look really complex for such a small calculator, it includes even a charger for the optional NiCd battery-pack. The later TI-1750 removed most components like the LC-8M did.

In later redesigns both the internal electronics and the LC-display were changed. Don't miss the second LC-1, the LC-2, LC-3, LC-4, LC-5, LC-6 and a later LS-6.
