Congratulations. I suspect you have the honor of receiving serial

Good guess but 03 went back for flashing with a new S3. It's a
well-tested board though.
It was worth a shot I suppose. :)
One important thing to note. The XC3S4000 is not supported by the free
Xilinx webpack. Unfortunately list price for the ISE Logic Edition is
something like $2.5k. This has obviously been a problem for people
wanting to contribute to the project. We don't have a solution for it
yet.
Can it be driven by the command line?
Yes, but the license is still needed to generate the bitfile an the big
problem is that the webpack doesn't even come with the datafiles for the
3S4000.
Specialized may be a bit of overkill, but yes you do need the Lattice
programming cable. I have one I got with a Lattice eval kit that I am
going to test when I get a moment. I suspect that if you have a bit of
experience with soldering, you could probably make one.
Lattice was very good about donating one to the project. I suppose I
should investigate a discount for sale OGD1 users. Note that it is not
yet supported by urjtag and... requires 32bit Windows.
Perhaps we can find someone interested in fixing this problem. I
haven't tried running the XP10 tools under Wine yet, but that would be a
bit better than having to have a full Windows VM. Just have to address
the programming problem.
As far as ISE goes, perhaps at some point we would approach Xilinx to
either donate licenses are perhaps provide deep discounts for
"community" or "educational" licenses for ISE.
