I have a few VR201 boards I might let loose. I don't want to sell any
monitors until I fell off the DECMATES , Rainbows, and Pros.

Greetings,
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 Coupled
RS-170 signals and to convert to RS-170 (NTSC black and white) I needed to
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
nothing else.
I tried to google this, but found nothing. My google foo has failed me.
Does anybody else have a working setup?
