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."
