The Raspberry Pi has become the most popular British computer yet made.
The title was formerly held by the Amstrad PCW which is believed to have sold a total of eight million units.
Sales of the Raspberry Pi will surpass that figure this month, said the Raspberry Pi project founder Eben Upton.
The milestone comes as the Raspberry Pi 3 is unveiled featuring a faster 64-bit processor and built-in wi-fi and Bluetooth connections.
“We’re calling it,” said Mr Upton. “We’re the best-selling UK computer ever.”
He said the Pi Foundation initially thought it had won the title last year when sales blew past the total set by Sinclair machines in the 1980s.
However, he said, it then emerged that the Amstrad machine had sold in larger numbers.
Now, even that total has been exceeded.

“The curve keeps trending upwards,” said Mr Upton, adding that sales will get a fillip from the release of the Raspberry Pi 3 on 29 February.
It will go on sale for £30 and a “few hundred thousand units” will be available on launch day from online stores.
“The two main things that people do with their Pi are use it as a PC replacement or use it as an embedded computer,” Mr Upton told the BBC.
“The Pi 3 is doubling down on both those things rather than going looking for new things to do.”
