Altera DE1 MSX by Caro and the RGB cable

Hello there

I've been a happy user of the Caro core on my DE1 for some time now, and I've just got an RGB cable for it: it's an RGB cable made for the original OCM, made by BAS: http://www.bas-ditta.info

Its a great-looking cable, but it doesn't really work with my Altera DE1 OCM. So I wanted to ask: should it work, Caro? or is your core missing something?

Of course I've played with SWITCHS 0-1 in all different combinations...

Thanks!!

Any news on this, Caro? Did you try the RGB cable?Yes, I have tried to connect OCM on DE1 through SCART.
In addition has connected to contact 9 plugs VGA +5V through the resistor 100 ÐžÐ¼.
It is necessary for making as 9 contacts VGA is connected to 16 contact SCART (input BLANKING).

16 - Input BLANKING
75 ohm input and output impedance.
0V to 0.4V: TV is driven by the composite video input signal on pin 20 (default if unconnected).
1V to 3V: TV is driven by the Red, Green, Blue signals and composite sync signal on pin 20.

Works wonderfully.
