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.
