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.
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.
