Early, prototype, electronic calculator produced by high-school student.
The first electronic desk calculators of the 1960s and early 1970s were very large and VERY expensive, but were versatile, quick, and silent.
If you only wanted to add lists of numbers then mechanical and electro-mechanical calculators were fast and still cost effective into the early 1970s, until the price of the electronic ones plummeted.
There was a general reduction in size, number of electronic components, and cost over this period. For further information see the section on The Calculator Business and the section on Calculator Electronics.
