You can find the product announcement in the Annouce mailing list archive here:
http://lists.fixstars.com/pipermail/yel ... 00218.htmlHowever, I don't believe there have been any official announcements from Fixstars about what has happened. If you go back to November 2008, you'll see Fixstars aquired Terra Soft Solutions:
http://lists.fixstars.com/pipermail/yel ... 00192.htmlBut since then, Sony released the PS3 "Slim" with no support for installing another OS such as YDL, and indicated this would be the case for all future models. Obviously, without a supply of new PS3s that can have Linux installed on them, this would have an effect on their product lineup.
http://www.playstation.com/ps3-openplatform/manual.htmlNot long after that, Fixstars' store (where the PS3s with YDL pre-installed, the bootable USB drives, etc., were sold) went "down for maintenance." Later, the support info that was on us.fixstars.com moved to
http://www.ydl.net, and us.fixstars.com now points to
http://www.fixstars.com.
So I'm not sure if that product is still available or not ... best thing to do would be to contact them and see:
