The Guardian newspaper informs about this with reference to the inventor's daughter Belinda Sinclair.

She added that her father died at his own home in London after a long illness.

It is noted that in 1982, Sinclair's firm released the ZX Spectrum 48K computer.

It used a tape recorder with cassettes as an information storage device, and instead of a monitor there was a home TV. 

This computer was highly valued for the ability to learn the basics of programming, for example, the popular BASIC language at that time.

Earlier it became known that an outstanding specialist in the field of mathematical modeling and computational mathematics, Academician of the Russian Academy of Sciences Anatoly Konovalov, died.
