Component to RGB question

Greetings all.

Back in the day, as they say, my husband used an Avid Media Composer for his production business. (So far back in the day that a certified Avid 9gig drive was $3000USD).

Anyway, you could get a cleaner signal onto your drives if you went Component to RGB. I built a conversion box myself with boards from Nova.

The connections are bnc, not rca.

Is this sort of box of any value to the folks who need to convert into their projector sets, etc?

Or does the fact that they’re bnc kind of make it a nice paperweight?

Any direction would be helpful. Just need enought o know if I put it in the Free or Electronics section of craigslist.

Best regards, and thanks in advance for any info.
