Re: Analog NTSC to RGB converter?



Thank you Michael for the usual good advice!

I know - I have modified another 1084 for NTSC in the past (then managed
to destroy it shortly after that). I might even be able to jury-rig some
kind of switchable solution (using some small relays maybe?), but I'm
kind of nervous whether I can pull that off without blowing this thing
again. That's why I'm looking for a nice-and-easy plug-in solution this
time...

Yeah, I figure that's what that schematic seems to hint at...

I found one, but they want $267 (sic!) for shipping to Germany:

There's also a PAL-NTSC format converter, which might do the job I want
as well, trying to find out:

And there's also lots and lots of the opposite - RGB to NTSC converters.
They seem to be in much higher demand.
