Canon Calculator 1210

The Japanese photographic company Canon made an early prototype of an electronic calculator in 1963, but did not take it further until other companies had shown that such devices would be marketable. Once production was underway, however, their success ensured they would out-last all their rivals.

This model was introduced in 1969. For the technically minded, it’s a compact 12-digit machine with a constant function and a single accumulating memory. The circuitry uses 68 DTL-SSI chips from the Texas Instruments SN3900 and SN4500 series, and a single TTL SN7400. The machine has a reed-switch keyboard.
