I am in a process of fixing a Dragon 32 - Issue 2 mobo.
I've finally sorted out Power supply but I am still having problems with video output quality.
On youtube, I saw examples of very crisp output via DIN/Composite but in my case, it is IMO poor.

Could you guys, confirm that it is either normal or indeed something is wrong with it?
And if it is wrong, then could you throw some hints on where to look for a cause?

Ok, I've fixed it
It turned out that I've supplied -12V instead of -5V. Now it works perfectly fine

Now I am trying to figure out how to upgrade it to 64k - manual here http://archive.worldofdragon.org/index. ... _Circuitry.
is a bit confusing
