Well, it seems to be an old system. (the device is 70ies or even earlier). Does anyone knows something about old or recent japanese color codes? I tried a google search and found absolutely nothing. I feel that this is still missing in our list.
GDR and Hungary go like old German/Austrian colors.
BTW, is cubrilo, our member from former Yugoslavia still around? I'd really like to know more about old yugoslavian wiring.
