We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Sinclair Sovereign Gold

The Sovereign was one of the last calculators to be released by Sinclair before the company refocused on the personal computer market. It was released in 1976 and can display eight digits in its red LED display. It features the usual four arithmetic functions plus square, square root, percentage, and memory. Because 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.

This is the special gold edition, and although it was made for more upmarket sales, it still used the same power hungry red LED technology, it also cost £30, which in 1976 was a huge sum of money, around £220 in todays money.
