This is the easy way to create this kind of cable as you only need to solder 6 wires.

You need:

-A standard VGA to VGA PC cable.

-A Male Scart connector

Cute the VGA cable (the size you want).

Here are the wires you need to keep:

3 BIG wires : RED, GREEN,BLUE

2 THIN wires :  TRANSPARENT, WHITE

You can remove all the others.

Now here is the SCART connector :

Solder the RED to 15

Solder the GREEN to 11

Solder the BLUE to 7

Solder the TRANSPARENT to 20

Solder the WHITE to 16

Don’t forget to solder the GROUND of the VGA cable to 21.

You are now ready to enjoy the Minimig on your 15KHz monitor. (Don’t forget to change the jumper position on the Minimig).

Enjoy!
