That's useful to know.  I plan to scrap an LC next week, but if anyone
here can make use of its 10baseT card, I will save it for them.

I /think/ I still have a Performa 638CD somewhere, which is probably
similar to the Quadra 630.  It has a TV tuner card that works under
System 7.  I don't know whether the TV tuner card is capable of video
capture or whether it's more of a genlock. I doubt it's supported, but
I'll happily sent it to anyone interested in writing a driver.  I read
somewhere that I/O performance on the 638CD was dismal.  Is this true
of the Quadra 630?
