The Need for Open Hardware
bwt asks: "With all the talk of DRM lately, it occurs to me that the entire concept depends on limiting the choice for computer hardware. OK, so the proper reaction to the copyright industry's attempts at PC market control is to be able to build a PC that they can't control. I know there have been some discussions on open hardware, but most if it was prior to the emergence of DRM as a real threat. In fact, Richard Stallman wrote an editorial in 1999 and said 'Because copying hardware is so hard, the question of whether we're allowed to do it is not vitally important.' DRM has perhaps changed that. Isn't the need for open hardware becoming critical? What is the status of the open hardware efforts?"
There's always OpenPPC.
To quote the site: "The immediate goal of the project is to enable interested parties to build inexpensive, PPC-based Linux boxes from IBM's reference plans. In the longer term, we hope to expand the open-source ideals expressed in the GPL to hardware projects, primarily motherboards."
There are a lot of open hardware designs at www.opencores.org.
CPU cores, Ethernet MACs, complete SOC designs, etc. It's a great site, especially if you are into fpga development.
The European Space Agency has made available VHDL for a CPU that implements the SPARC V8 instruction set. The VHDL is available under the GNU LGPL license. Granted, implementations of LEON are slow (25 MHz?) but it's totally freely available. You may need to buy a $99 license from SPARC International to actually sell any CPUs you make, but that's pretty cheap.
The SPARC instruction set is pretty simple. I don't imagine that a similar effort for x86 CPUs would be as simple or as quick.
Quit playing Monopoly with Bill. Switch to one of many non-Microsoft products today.
A brief introduction to the simputer to those who don't already know:
"The Simputer is a low cost portable alternative to PCs, by which the benefits of IT can reach the common man. "
The system software is available under GPL, and the hardware specs under SGPL, the full licensing info is here.
With a $99 FPGA development board and the free design tools from Xilinx, you too can make your own CPU without even breaking out a soldering iron. :)
What concerns us most is the thin layer between hardware and software: items like the BIOS and flash ROM. That layer is ripe for DRM and other technologies. That issue is quite different from Stallman's essay mentioned in the post. This isn't an issue of Free (as in freedom) hardware, but is about a matter of that "thin layer" of software where DRM will likely dwell.
FSF is currently extremely short on resources, but we hope to put at least some force behind initiatives to create Free Software in this area. In some sense, it is the last frontier for freedom on our computers. Indeed, the only proprietary software code anywhere in my computer is that which lives in the BIOS. Before now, the issue was not so strategically significant, but the fact that DRM technologies may soon live in that very BIOS makes it more significant than ever.
If anyone has an interest and reverse engineering experience, and would like involved with working on the free BIOS projects, particularly for laptop devices, please contact me. Also, please contact me if you would like to donate to a restricted fund for this effort, as we are considering setting one up if there is substantial interest.
Sincerely,
Bradley M. Kuhn, Executive Director, Free Software Foundation
The whole problem with DRM is that anytime someone can choose between having it or not, they will almost always choose not to have it. This is elementary common sense.
Manufacturers are rightly scared of DRM for this reason. Anything too radical or obstrusive will kill sales. And what MPAA/RIAA wants is highly radical.
They are thus pursuing two avenues around the problem. The first is to make DRM a part of Windows. Since as we've observed most users (for a variety of reasons) are locked into Windows, they will have no choice but to (eventually) upgrade into DRM. There are some problems with this approach; they (correctly) don't trust Microsoft, either to do a good job or to look out for their interests, and there are those pesky "competitors." Will Apple play ball? Think about it. They'll have a powerful incentive not to, to try to use the Windows-DRM shock as an opportunity to gain marketshare. But of course, as has been well established in the past, Apple can be bought. That still leaves Linux. And that's a bit frightening, frankly, since you can't reliably control Linux, and the buzz on the street is that, someday, it might be what everyone uses.
That brings me to the second prong of this attack: the CBDTPA, in its many forms, past and (undoubtedly) future. And that, basically, would make "Open Hardware" illegal. If past legislation is any guide, it would probably also make talking about how to build open hardware illegal.
So if you're considering spending time and energy getting involved in the design and (god forbid) manufacture of open hardware, please don't bother. If you're determined to contribute to the issue, you're needed in Washington.

gEDA is also a good project for Linux people interested in open hardware: they develop a GNU liscenced set of hardware design tools.
Just my bookmarks two cents on the topic.
All circuits busy.
