You can just make a new one yourself, by using the 2 current headers, a new ribbon cable and using the old shielding. Did it myself previously, works like a charm.

Cool,

Is there anyway of making a shielding cable as the one on my current lead was burned off by the previous owner of the card. They messed up and the cable caught fire. I though i'd patched the issue for now! I will see to making a new cable :o)

I would assume that you can find a new shielding tube and isolation tube at the same place where you buy your ribbon cables.

I was going to use some spare ribbon cable and DIY the shielding/Isolation tube

Hi, I would actually caution against this.  I'm not sure of the shielding configuration of the original cable, but I'm assuming it's a grounding braid, enclosing a ribbon cable.  Is that right?  You can buy shielded ribbon cable from good electronics suppliers.  Usually, buying shielding separately costs a lot more, makes a lot more work, and usually gives a considerably inferior reault.  One important consideration is the attachment of the shielding at one or each end (depending on the requirements of the design).  The quality and coverage of the attachments can make a significant difference to the shielding factor.  For some cables, the shield is also the primary ground conductor, which is critical for good signal integrity.  If you are not experienced, achieving a high standard of shielding can be difficult and excessively expensive.

Does anyone have specifications for that cable, or even a photograph of an intact specimen?  I ask this as I may be able to give more helpful advice if I knew more about the cable.
Good good study, day day up!

Hi,

Cheers for this advice, I will look into the grounding issue. As I mensioned earlier in the post the previous owner of the card nearly murdered the cable  - including the ground cable. I have re-made the cable but have improvised on the grounding by using copper wound around the cable and soldered either end...It worked until the miggy was moved. Although I can get a very good image, Touching or moving the cable gives me a blured/unusual colour image.
