Renowned British inventor Cliff Sinclair has died at the age of 81, according to The Guardian. According to information provided by family members, Sinclair died at his home in London after a long illness. His daughter, Belinda Sinclair, said: “He was a wonderful person. Of course, he was very smart and always interested in everything.”

Cliff Sinclair was born on June 30, 1940 in the English capital. From a young age, he showed an interest in technology at the time, and when he was 17 years old, he dropped out of school to found Sinclair Radionics in 1961. Early in his career as an inventor, he showed his flair for portable devices and carrying technology to the masses.

However, the product that cemented its importance in the history of technology was the first pocket calculator, which saw the light during 1967. Clive Sinclair was really interested in reducing the dimensions of the devices that are so common today to carry. On the one hand. “He wanted to make things small and cheap so that people could access them,” his daughter said.

Through the experience gained with different models of calculators, Clive Sinclair entered the world of computers. In 1980 he introduced the ZX80, which at that time was considered the smallest and most expensive computer in the world. Its specifications are a far cry from what we can get today: 1 KB of RAM and an operating system based on BASIC.

The ZX80 was a complete success thanks to its low price, costing about one-fifth of other home computers. In subsequent years, he released new versions of the computer, with the ZX Spectrum (1982) the most successful in sales. It was distributed in two different versions depending on its RAM: 16 or 48 KB. The Zilog Z80A 3.5MHz processor is integrated and the computer can even emit sounds.

Without a doubt, humanity is losing a great inventor who helped bring technology to the widest possible audience. “It was the ideas, the challenge, what he found exciting,” his father, Belinda Sinclair, concluded. “He would come up with an idea and say, ‘There’s no point in asking if someone wants it, because they can’t imagine it.'”
