Back in the ‘70s was Elliott Automation, later Pico Electronics Ltd. Pico was formed in 1970 by George Stevenson, David Campbell, Harry McLennan and Les Leech. They had all worked at Elliott's and were wizards in calculator chip design. George was the Director of Engineering and with his team, they pulled off a single-chip calculator design. The microprocessor they designed was ahead of its time and far more advanced than similar chips that followed it for years to come. Actually, one of their microprocessors was the world's first microprocessor. George Stevenson patented it and years later successfully defended RadioShack against a lawsuit from Texas Instruments who claimed they invented the Microprocessor.

In 1971, the Monroe Calculator Company/Litton Industries became one of Pico's first major customers. Actually, Pico didn’t just sell them chips, they designed the whole calculator. A year later, Sinclair, Royal, Bomar, as well as many more, started using Pico's chips.

This calculator is one of the early models from the Pico days. A real piece of tech-history!
