Sun to open-source SPARC architecture
Sun's open-source evangelist, Simon Phipps says that "the Verilog source code, tools and more behind the UltraSPARC T1 (the "design point") will be released under an OSI-approved open source license next year." They will supposedly be trying to create a hardware development community around SPARC computer architecture via OpenSPARC.net.
Given that the SPARC architecture has, like MIPS, been relegated to the "who cares" leagues in recent years, this move is a chance for Sun to (try to) save its hardware-based lifestyle. Of course, it remains to be seen what all of the details are in terms of things like patent and trademark legal land mines.
Of course, for those following along, look at how Sun's "born again" take on open source is proceeding everywhere except for the Java core. That's an awfully good indication of where Sun thinks the real power is (and what they are afraid of losing their control of).
