    Hardware documentation:

    +Previous to 2007, it was extremely difficult or impossible to get much of +the neccessary hardware documentation for these machines. Members of our +team (in particular David Gwynne) were instrumental in pressuring and +convincing Sun to go back into their archives and dig up the data sheets +that they had written in-house, describing the operation of their chips to +their own engineers. These documents can now be found at + +http://wikis.sun.com/display/FOSSdocs/Home. +Some documents are still missing at that site, so we ask that interested +developers contact Sun and request additional information.
