Master System 1 and Mega Drive 1 Scart Lead (Continued)
If you can, find something to hold the 8 pin din plug for you, if you haven't' got a set of helping hands, then improvise, don't use anything that doesn't like getting hot, as the pins will get hot during soldering. With the socket secured, melt some solder into each of the pins, ready to solder the wires into place.
BEFORE you do any soldering of wires, make sure you slide the plastic part of the plug down over the cable, ready for re-assembly later on.
Now strip the cable (about 2cm should be okay), then "tin" each of the cables inside. For the wire attached to the shielding of the cable (it's just bare wire) twist it up so it's neat, ready to attach to the metal barrel of the 8 pin din.
Now simply follow the table above, and solder the correct coloured wire to the correct pin. It's probably best to start with the Blue signal first (pin 8), as it's right in the middle and would be difficult if left until last. Simply press the soldering iron onto the pin, near the hole, when the solder inside melts, push the wire into place. Work around soldering the rest of the wires. Notice you won't be soldering a wire to pin 7, it isn't used.
Re-assemble the plug, first of all wrap the the bare shielding wire around the cable grips, squeeze the grips together, then put the other half of the metal barrel in place. Finally, slide the plastic part of the plug over the metal barrel.
You can clearly see my TV is displaying an RGB signal from a Master System. It is a big improvement.
mmmonkey first found the pin layout for this cable over on Mike Gordon's website, so credit must go to him.
