Congratulations to Nick Andrews, aka Kalamatee, who just finished to port AROS(*) to the raspberry Pi:
(have a look at the platform in the About window)
It is missing some USB part to be fully complete, but for now boots to the board, the Wanderer.
We, the AROS Dev Team, hope this port will get interest from the RasPi community, because of its small footprint, its speed, and its ease to develop for as much as the Amiga community which could find again the sensations of its glorious times.
(*) The AROS Research OS is a reimplementation from scratch of the Amiga OS, while improving it in many areas. ( http://aros.org )
