Excellent!

Do you have audio via RF? If you do, then you’ll probably want to make sure pin 3 of the DIN connector is connected to both pin 2 and 6 of the SCART. If not, then it’ll make sense to see whether you’re missing both the sound from the gate array and the AY chip or just the AY.

Managed to get the cable working last night by moving the 12v wire to pin 1 ( it was on pin 3 ) there is no sound yet but the audio wire is connected to pin 5 and not 3. I bought this cable from Cool Novelties and it's the first time I have used them.

I’ve used Cool Novelties for RGB - SCART cables before (can’t remember if I have ever got one for a +2A/+2B/+3 from them though). My most recent cable for them was for a Acorn BBC/Master/Electron.

When you say you moved the 12V wire to pin 1, I presume you mean in the DIN plug.

Yeah all the pin moves I have talked about are all at the DIN pin. I got the sound working this morning by doing the wire move so the cable works now. My new cable from Retrocomputershack arrived this morning and worked from the get-go. I’m not sure what happened with the other cable maybe someone had a black-out but It’ll do as a spare or if I need to kit bash a cable.

Glad you got the entire thing sorted out!

Well, 8-pin male connectors are a little more tedious to solder than your common 5-pin jobbies. Then again, nothing beats the 13-pin DINs for my Roland GR-55 system. Boy, was that a fun time.

Atari ST’s use a 13 pin DIN for the video output connector, and a larger 14 pin DIN for the external floppy drive port...
But mini DIN are the worst...
