Ugh. Sounds tricky.  My best advice would be to get the system to forget
about using the card for real work, and to copy the screen every vertical
blanking interval.  (No, I don't know of any software to do that)
But that seems like it will SLLOOOWWW the system down.
Wouldn't it be easier to get a Y-cable and a hardware RS-170 to NTSC
converter?
