RGB switch = scart pin 16 = mini DIN pin 2. Put an 180 Ohm (or 150 Ohm) between.
RED = scart pin 15 = mini DIN pin 7. Minus of 220 uF capacitor on scart pin 15 & 75 Ohms resistor on + and DIN pin 7
GREEN = scart pin 11 = mini DIN pin 3. Minus of 220 uF capacitor on scart pin 15 & 75 Ohms resistor on + and DIN pin 3
BLUE = scart pin 7 = mini DIN pin 1. Minus of 220 uF capacitor on scart pin 15 & 75 Ohms resistor on + and DIN pin 1
Synchro = scart pin 20 = mini DIN pin 4

2. MD2 Switchless


Material:
-1x pic 16F630
-Seb code (see link below)
-Pic writer
-2x 22O Ohm resistors
-1x PNP bi-led
-Check pictures for detail of installation.

Installation picture big size

-Check 315-56600-02 chip

-Cut the circuit from pin 46
-Link pin 46 to pin 10 of pic (pin 46 to GND = 50Hz; pin 46 to 5v = 60Hz)

-Cut the circuit from pin 107
-Link pin 107 to pin 13 of pic (pin 46 to GND = JAP; pin 46 to 5v = ENG)

-Cut the circuit to the reset button from pin 78 -Link pin 78 to pin 11 of pic (Reset function) -Link reset button to pin 9 of pic (Interception of reset impultion)

-+5v to pin 1
-GND to pin 8
-Pin 5 & 6 are +5v to cathode of bi-led, anode to GND. How it work:
Quick press on reset button make reseting the console
Half second press on reset button make frequency (50/60Hz)
One second or more pressing the reset button make change the region (US / EU / JAP), the led change color
