I'm trying to find a way to get my DEC Rainbow's monochrome output onto a
newer monitor than my aging VR201 (especially since I zapped something in
it and my diagnostic efforts to date haven't fixed it).
So, I found the bit in the Rainbow docs that said the output was DC
RS-170 signals and to convert to RS-170 (NTSC
black and white) I needed
put a 10uF cap inline to make it RS-170. So I did
this, and fed it into a
generic NTSC composite video to VGA thing, and got only a little joy. The
first few lines seem to be missing, then the next few are OK and then
I'd be interested in the answer also, for my Pro.
What device do you use for NTSC to VGA conversion?
and it's the one that's not working. Look to be dozens of clones of this
though.. My NTSC camera works with it..
