This credit card-sized calculator from Casio dates from 1980, two years after they released the LC-78 which was the world's first credit card-sized calculator. It is an example of how fast pocket-sized calculators developed in the 1970s with the improvements in IC and display technologies.

The calculator has memory, percentage, and square root functions, as well as being a metric converter. It has an eight-digit LCD (liquid crystal) display.

Our calculator was very kindly donated by Francis Hookham.
