The first Raspberry Pi was released in 2012 and more than 10 million have now been sold
The makers of the tiny Raspberry Pi computer have created a version of its operating system that can run on ordinary desktop computers.
The Pixel OS has been re-worked so it runs on PCs and Apple Mac machines, said the Foundation.
The release means Pi fans can write software on one Pixel device and use it on another with no changes.
The Pi Foundation said the release also aided its plan to produce the "best" desktop computing experience.
Raspberry Pi co-creator Eben Upton said the software should help schoolchildren who use the credit-card sized Pi in class or for their own projects but have to continue their work on PCs or Macs.
