The video port pinout from my previous post led to some succes with my UKNC (Elektronika MS 0511) Soviet-Russian computer.

Today I made a SCART cable to connect the UKNC to my old Bang&Olufsen CRT TV. (that still needs replacement with an equally pretty LCD TV ;) )
It seems the B&O does understand the video signals from behind the iron curtain. :)

The SCART wiring is pretty simple, I've connected RGB, sync and composite-video and used a common ground on the SCART video ground line.
I think the TV is using the RGB inputs, because when I tried feeding the composite video with a cinch plug earlier, I didn't get the TV to sync.

I recently bought a old Soviet PDP-11 compatible computer on Ebay, the UKNC (УКНЦ in Russian) an educational computer system with a formfactor somewhat like the Amiga 500.

I'm still struggling to bring the machine back to life, the biggest hurdle is that most of the documentation about this machine is (of course) in Russian only, and I don't speak any Russian at all.
Google translate is a big help, and translating to Russian to Google for information helps a lot.

This way, I finally found the pinout of the video connectors on the machine, these are 10-pin headers on the back of the machine, labeled "вм".
To document this for myself, and maybe for someone else whom might benefit from this, I've posted the pinout of these connectors here:
