here is my experience.
i connected pin 6 to 20 and then pin 4 to 16. it gave me fantastic rgb picture with one small problem; the panasonic tv would occasionally 'detect' again that its rgb (and not composite) and it would display 'RGB' in corner for a sec.
thats because we're not giving enough voltage on pin16. it was a bit annoying, so I connected +5V to 220ohms and then scart pin 16 (I left CPC pin 4 unconnected) and it works great.
btw, I didn't connect the blanking ground (pin18). tried it with first solution (CPC4->scart16) but then would only get black&white picture (composite?)
