Introduced: ca. 1985
The PiraComp SC-30 is a small and thin (credit card size)
calculator with memory and percentages. It is solar powered.
As can be seen on the picture, the calculator was used as promotional material, here bearing the brand name and logo of Becel. My guess is that this calculator was introduced around 1985 because that's when the Dutch butter-brand Becel had its 25-year anniversary (the company was founded in 1960).
