This
Canon Palmtronic LC uses a silver LC-display instead the yellow-type found with
the first LC-1. Another sibling could be found with the LC-2.
We are confused about the two LC-1 we discovered so far. The
model with the yellow LC-Display sports a lower (511365) serial number than this
LC-2 with the silver LC-Display. Nevertheless was the single-chip calculator
circuit of the first model manufactured in December 1976, while the chip of the
later calculator was manufactured already in November 1976. Probably were both
calculators manufactured in the transition time.
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.
