On my comet, I have to reseat the ribbon cable constantly. Is there a source that I can purchase a replacement from? And if so I assume it has to be soldered in. I did not find a good way to take the connector apart on the sound board end. Not a problem soldering if I could only find a replacement.

Correct. I have hundreds of them. What I do not have is the end that solders into the sound board that pokes thru the cable making the contact. I cannot seem to get it apart, and back in the day when I worked on vintage computers, that crimp connector does not re-poke the new cable properly again. Its like it was manufactured to be a one and done.

I was hoping for a source I could buy a new one.

Anyone know a source to purchase it already pre made?

To my horror, I reseated the cable for its last time yesterday and all sound was gone. I grabbed a hard drive cable, cut it with a pair of scissors to the correct length, and inserted it into the sound board IDC clamp. To help it pierce thru the insulation I used my hot air station set to 200 C, and heated the cable before attempting the crimp. I used a shop vise to reclamp the IDC and I have to tell you it worked!!!!! This is the first time I have ever gotten an IDC to clamp a second time. Usually it just breaks.

Turned game on and heard speech I have never heard before. After a quick autopsy, there was battery acid deep inside the ribbon cable. Im surprised I was able to reseat it as many times as i did.
