Video capture of 9-pin TTL RGB (such as that used by IBM CGA, Commodore 
C64, etc.) is something that I have been trying to do for a very long 
time, without appreciable success.  I even tracked down an old scan 
converter that claimed to convert TTL RGB to NTSC so I could grab it 
with a capture card turned out to not work (although it's possible the 
scan converter was broken).

I ordered a Video Turtle in 2001 which was supposed to do this same type 
of conversion but it never worked and the company disappeared before I 
could get tech support.

If anyone comes up with a solution that costs less than $200, I'd love 
to hear it.
