I wanted to make an adapter to use a standard SCART cable. It's a prototype in the photo. I need a housing and everything on one PCB. I was supposed to mill the plate but I have to think about it ...

Don’t get mad, but I wouldn’t trust an adapter in this state.
Gflorez is right. Try it with a suitable cable.

Great plug 4 EP64! Do you make them yourself? Maybe you have to sell? I mean the plug itself without a cable and Scart.

And that's it: an adapter! I made it without 19pin-20pin crossover and that's the effect. The first time I decided to do it on an adapter and my routine failed me. I forgot about the crossover. Before reading the rest of the posts, I decided to do without an adapter. IT LIVES! hahahahaha! The image is a bit bright but I will add a resistor and it will be ok.
I can see there is a really helpful community here - many thanks to YOU.

He does not get nervous :-)
I did two and both would be bad .... maybe.
I have to solder directly to SCART and then it will be sure.
I've already made several dozen RGB cables for various 8/16 bit and they all work ;-)
But it must be the first time sometime.
I will check without this grommet, let me know.

I tried 2 different SCART - SCART cables.
Today I will connect to the third TV and maybe the LCD TV.
I connect through this adapter of my job:
I have 2 of these, one with resistors, the other without.

You put it right: stable image. Yes.

And if SCART is connected, despite the bad picture, should there be sound? For example, beeping from the keyboard? Audible on tv -SCART.

I tried to connect A3 - no good change.
I tried to turn the coil - unfortunately it doesn't help either.
I checked the resistor - it's okey 100ohm.
I have 2 E64 units and both have the same problem.
The output from the modulator gives the "correct" signal ;-)   .

I connected the signal coming before the modulator, composite and the image is in colors and it does not jump but I want RGB and ...... ;-(

This is the effect of RGB as in the pictures below.

 I'm new to the forum. I bought an E64 from egypt and started it. I changed the capacitors and measured the power, it is 5V and 12V.
I made a plug for RGB - scart for TV. Here's the problem: it can't catch sync. The image is in color but it floats diagonally to the side and up and down. The resistors are RGB and CSYNC. First I gave 100 ohms, then changed to 330 ohms. 12V is connected to pin 8 on SCART and from 8 to 16 a 470 ohm resistor. There is still a problem. I measured RGB multimeter and it's 0.2V CSYNC has 3V. I tried to lower the Volts on CSYNC with a potentiometer (resistor) but it does not change either. The same effect is present on two TVs. I also have a second E64 and there is the same trouble.
I don't know what to look for. Can someone help me - give me a hint?
