Apparently it's also discontinued.  That's too bad.

I see that a Spartan 3L (low-power version) would take several times
as much power as the 2700G.  The million gate one (to cut it down a
bit, in comparison to which the OpenGraphics project is using the 4
million gate version) has quiescent current ratings of 35 mA for
internal supply plus 20 mA for AUX supply.  So if I understand
correctly that is the minimum, if it's turned on at all.  I suppose if
you are actively doing something, it would be several times as much.
The OpenGraphics board has a heatsink, after all.

That's a bummer.  I think programmable hardware would be an excellent
way for open software to innovate right around the barriers of
proprietary graphics chips.  But I don't have any experience at all
programming them yet.

There is the NVIDIA GoForce 4800 and I don't see datasheets for it either.

I'm still working with mine.  Angstrom is working well enough to do
the kind of hacking I want to do.  I'm glad the 2.6 kernel is finally

That's how it used to be.  A million-gate Spartan IIIE ranges from
about $20 down to $7.90 at Digikey depending on the number of IO pins
(I think you can easily get under $5 in volume).  Power would be the
problem with those chips.  I wonder who's the low-power leader for
