The Sovereign was one of the last calculators to be released by Sinclair Radionics before the company was split up and sold off by the National Enterprise Board. It was released in 1976 and can display eight digits in its red LED display. It has a Mostek MK50321N main integrated circuit, and features the usual four arithmetic functions plus square, square root, percentage, and memory. As the case was made of pressed steel instead of plastic it was available in a variety of styles, including black painted, chrome plated, silver plated, and gold plated.

Sinclair won a Design Council Award in 1977 for the Sovereign calculator, which was designed by John Pemberton.

This example in our collection is the gold plated version.
