I supplied the original pile of Blade 1000 and 2000 machines to Theo and the 2006 OpenBSD hackthon. You should take an OpenBSD sparc64 snapshot and try it. It is extremely usable and stable. Mark Kettenis has made huge leaps in working around the myriad of bugs in the processor and associated glue logic. Ultrasparc III running OpenBSD is solid and keeps getting faster. Originally, the initial patches and commits had extensively IFDEF work to ensure that earlier versions of Ultrasparc wouldn't break. The code has been fully integrated into the tree for a number of months. Also, a few days ago Mark committed a driver for the Cassini network controller chips. --Jason
