LC-1_S_Back.jpg (171002 Byte)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.

LC-1_S_PCB.jpg (236508 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.
