Retro parts is clearly a "niche" market.
"IF" you are lucky and can find someone who is looking for that part, you can make some money. But chances are, you won't find anyone. So then you need to decide, is it rare and belongs in a museum? Possible, but probably not.
So what do you do with it?
I was in that place a couple years ago where I had a entire room in the basement full of old motherboards, CPUs, coolers, graphics cards, memory sticks, PSUs, cases, monitors, printers, stereo and A/V electronics and speakers, TVs and more. Stuff "
I might use or need someday." My family started accusing me of being an electronics "hoarder". Well, "someday" never came.
I then discovered we have an electronics recycling center in my area. I loaded up my truck and hauled everything out there. They paid me $80 for the precious metals in the processors and memory chips, and for the scrap aluminum and steel. That made me less sad to see it go. It was also reassuring to know all the hazardous waste found in electronics would be properly recycled and disposed of, instead of getting dumped in landfills and ending up in our water supplies.
They only thing they would not take is a bunch of old CRT monitors and TVs - unless I paid them $10 each. There is a tiny drop of mercury inside cathode ray tubes. To extract it, one must pop the end of the tube off carefully or risk a very dangerous implosion/explosion of flying shards of glass due to the extreme vacuum in those tubes. Then there are very strict standards and laws for disposing of mercury in environmentally safe ways. So there is no money for the recycling centers in recycling CRT monitors and TVs. So I took them back home, printed out a "Free" sign and started lugging them out to the curb. By the time I was taking the 3rd one out, some guy in another truck was loading the first two into his truck. He grabbed the rest and I now have a nice guest bedroom in my basement.
If "someday" has never come for you, I urge you to look into disposing this old stuff through proper electronics recycling centers. Don't just toss them in the trash.
