Hi,
not contented to have fried a MD in the process, I'm still into SCART modding some old consoles.
Some years ago I mistakenly boutght a french NES without cables, as I thought I could use my old RCA.
Now I'd like to add a female SCART connector, and I found the original cable pinout (somewhere in this forum).

Assuming we're looking into the end of the cable, pinout is:
1 Video / luminance
2 Right / mono audio
3 Blue video
4 Ground for right / mono audio and blue video
5 Green video
6 Ground for green video and red video / chroma
7 Red ivdeo / chroma
8 Ground for video / luminance / blanking <--- forgotten on my handwritten diagram
9 Blanking
10 Function switching
I also found out how the pins are soldered on the mainboard, so now I need some help to draw a good diagram.
My idea is to connect the pins on the mainboard to the female OUT SCART connector:

to here http://djlooka.altervista.org/FemSCART_inside.PNG (http://djlooka.altervista.org/FemSCART_inside.PNG).
My guess is:
| M/B pin | | | SCART pin |
| 1 | | | 19 |
| 2 | | | 3 |
| 3 | | | 7 |
| 4 | | | 5 |
| 5 | | | 11 |
| 6 | | | 9 |
| 7 | | | 15 |
| 8 | | | 18 |
| 9 | | | 16 |
| 10 | | | 8? |
Any guesses for caps/resistors?
Thanks in advance,
Ok, so my bad luck is not leaving me...
Today I was going to try this SCART mod, but I discovered that my frog-eater NES is *already* dead! x__x'
At least, it seems to have the "blinking led of death" http://josh.kfoo.net/9-nes-console-repair.html (http://josh.kfoo.net/9-nes-console-repair.html), which I couldn't fix by polishing the contacts...
I'd like to post anyway my corrected diagram, just in case...

Frog eater? That's not very polite! :P
Disabling the lockout chip of the NES (http://mmmonkey.co.uk/console/nintendo/nes-lockout.htm) doesn't just make it able to play foreign NES carts, it also prevents the NES from constantly resetting. If you still get only a grey image your carts probably need a cleaning.
