Make sure the pin numbers used from the link are from looking at the cable (some pinouts use numbers when looking at the socket in the computer) if the cable was made with the wrong point of view the pins would be mirrored left/right.

Use this image as a reference:

And those other micros use the same SCART socket in RGB mode?

Yes.

Besides the line, do you get audio (beep @ boot, keyboard click) when you connect your MSX?

I don't remember, and I have given this cable back for correction so can't check again.

@sdsnatcher73: I did open it myself and checked it vs that image, the connections seemed right to me. He also had it as reference when he was making the cable. I can ask him to double check again but I suppose the make itself is ok.

I guess I'd like somebody to confirm that they have succesfully used this particular pinout on a Japanese Panasonic F1-AS (or similar) + Euro CRT TV, then I'd know the problem is somewhere on my side.

PS: the only difference is that the guy used female socket SCART in this cable, instead of male. But I think the pinout should be the same?

I'll probably order this cable from Spain anyway: http://retrocables.es/tienda/index.php?id_product=53&control..., kinda gave up hope on getting this to work.

This page has been online for a long time and several people are being used to make his cable with success. Me too.

Ok, just a couple of questions then:
You are sure you used the RGB DIN port on the computer, not the TAPE DIN port, right?
Is the computer in a working condition? I.e. no damaged HIC board or fractured solder on the DIN connector?

You mean you used a female SCART socket and then a male-male SCART cable to connect to the TV?
If you did that it won't work as female SCART sockets should be wired differently.

The computer is fine as far as I know. I've been using it for some time now via composite. I bought it from sdsnatcher73 and I trust that he tested the RGB output properly.

Yes, the connection is DIN8 - female SCART + SCART - SCART cable into the TV. Are you sure the female SCART has different pinout? If yes, is there a diagram somewhere?

SCART sockets/plugs have input and output pins. Commercial Male to Male SCART cables are internally wired to pick some signals from the output pins and place them to the inputs (and vice-versa) so they aren't simply wired straight.

In your case the RGB and voltage signaling can be left as is, you only need to change the 2 audio lines and the CVBS/SYNC.
If you are using a male plug you normally put audio on pins 2 & 6 and Sync on pin 20, but on a female socket you'll have to use pins 1 and 3 for audio and 19 for Sync.
And also connect more than one GND wire, there's absolutely no guarantee that the TV will have all the grounds internally connected.

Oh and also you have to make sure to use a fully wired Male to Male SCART cable, as the cheap ones do only work with composite.

Alright, thanks. I think that I'll do the last roll of the dice and just ask him to get rid of the female socket and wire it to male one as it was originally intended. Not sure why he used the female one, maybe got confused because he's making a couple other cables for me.

If that doesn't work then I'll give up and just buy that cable from Spain.
