Twenty Years of RISC OS Open
On 20 June 2006 we incorporated RISC OS Open Ltd with one slightly mad ambition: to take a proprietary operating system and open it up to anyone who fancied helping. Twenty years on, that has largely happened, and the RISC OS of today is in far better health than the one we inherited. To mark the occasion, here is the story so far, with one highlight for each of our first twenty years.

Our thanks go to everyone who has written code, filed a bug, funded a bounty, contributed in our forums and wiki, tested a nightly build, or simply cheered from the sidelines.
