I would like to share a solution to a noisy video screen 
I have been doing some 2600 coding and downloading to the real thing with my Cuttle Cart but I was having problems with a >lot< of noise on the video screen. 

I had a couple of snap-on ferrite filters lying around so I put one on the cable from the VCS to the TV and one on the Cuttle Cart audio cable attached to the PC sound card.

This worked much better than I expected and I now have a crystal clear image (and less image roll) for developing!

For reference, I used TDK ZCAT2032-0930 which is 80 ohms at 50-500Mhz with a 9mm (little over 5/16") internal diameter. Fits cable ok (it's at home, so I can't check the clearance)

specs at:

Picture of similar but smaller internal diameter.

Also avail at DIGIKEY search for "ferrite core snap on"

DIGIKEY spec sheet on ferrites


Maybe this would work but it has 6.5 mm internal diameter.
