This page is now historical, as RISC OS Pi is now available
Raspberry Pi was expected to launch towards the end of 2011 but was, in fact, launched on 29th February 2012 with the first production boards reaching users in May 2012. The lead time on orders was initially about ten weeks but the Revision 2 board (made in UK) is now (mid Sept 2012) available from stock (5 days delivery) from Farnell. The opportunity to produce a polished RISC OS distribution for it was recognised, which will potentially have a large audience. Before full release, there were a number of areas of RISC OS that need attention. A ‘pre-alpha’ version of RISC OS on the Pi may now be downloaded.
