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? Warner
