That's exactly what I was looking for!
A USB capture device is very slow. Firewire is much faster (but expensive).
I didn't even think there was a PCMCIA card that did that sort of thing. But that would be the way to go. It would be much faster than trying to get 25fps through USB. There are USB capture devices but if you want the full frame rate, then it comes down compressed as mpeg, which is no good for astronomy. And with uncompressed images you would only get 5fps (maybe).
So PCMCIA is the way to go. Nice find!
