I'm wondering why you'd want a *DC10+* for such a job, where a webcam
would normally be more than enough!

Well, the thing is, the DC10+ does DMA capture, so it needs some free
physical memory for capture. For a webcam, any kind of virtual memory
would generally be enough, as the data comes in over the USB bus and
doesn't need DMA or anything.

Make sure you have a few 100 kB (or better yet: at least several MB) of
physical memory left before trying to use the DC10+. 64 MB should
generally be enough, depending on your environment. I've ran the DC10+
inside Blackbox + X 4.x on RH70 for a while with 64 MB RAM, but for
heavier Desktop environments like Gnome-2.x or KDE-3.x, I'd recommend at
least 128 MB of RAM.

Oh, and 350 MHz is enough, some people use such a card on ~ 200 MHz
machines.
