The first prototype - 2006
While the $35 Raspberry Pi has redefined our idea of what a cheap computer is, the path to creating the board certainly wasn't easy.
This gallery charts the history of the Raspberry Pi, from the very first prototype to the finished board that launched in 2012.
2006 Raspberry Pi prototype
Created by Eben Upton, the first Raspberry Pi prototype was very different to the Pi that would launch in 2012.
The machine may have been rudimentary but had the advantage that it could be manually assembled and soldered.
The downside was that it was rather weedy, even by 2006 standards, roughly as powerful as the BBC Micro that Eben Upton cut his teeth on in the 1980s.
