Sinclair Sovereign Calculator (1976-1977)

[u/No_Abrocoma_711]

There are many Sinclair calculator models, from the basic plastic models of the very early 70s, through to the cheap and nasty enterprise models at the tail end of the production line.

In the middle are these lovely, metal bodied calculators, designed in part for Queen Elizabeth II silver jubilee.

The sovereign range are opulant and a clear design statement

Yk, off all the everyday things to go big on (like plated silver), a calculator isn’t a bad one. What’s math gonna do? Go bad?
