On This Day: March 5 1981 Sinclair Research Released the ZX81 Home Computer
On this day March 5 1981, Sinclair Research released the first British home computer, the ZX81. The ZX81 was designed to be an affordable and accessible personal computer, aimed at the growing home computing market.

The computer was priced at 50 Euros for the uninstalled version and 70 Euros with installation. Despite its low cost, the ZX81 was a significant milestone in the development of personal computers, offering basic functionality and helping to popularize home computing in the UK and beyond.

The ZX81 sold over 1.5 million units worldwide, making it one of the first major successes in the home computer market. Its simple design and easy-to-use interface helped introduce a new generation of users to the world of computing.

Fun fact: The ZX81 was one of the first computers to include a built-in BASIC programming language, which allowed users to create their own programs.

Trivia question: Sinclair Research released another home computer in 1982 that became even more popular than the ZX81. Can you name this computer?
