Finally I found some time to start soldering. I managed to finish the Reset circuit, composite gen, mono gen, audio gen, DAC circuit and RGB/Mono switch:
I believe you should take a gander at cr14. Looks like it maybe in backwards. :)

@PaulJ Wow, thanks! You probably saved me hours of looking for that one :)
Which motivates me to upload better pictures of my progress, you never know if someone is nice enough to have a look at them :mrgreen:

@IngoQ when people post pictures I usually look for obvious mistakes, @PhilC usually makes em easy to spot like putting the reset chip in perpendicular to its intended position.

I know @PhilC , you did throw in the backward diode in addition to the reset chip. You thought you could sneak that one in figuring I'd give up after the reset find. :mrgreen: :mrgreen: :mrgreen:
