I wasn't sure where to post this but here it is. I have searched multiple times but can't find what they are. I have someone who clears out old offices and houses etc and he always has piles of tech stuff he gives me. 90+% goes to the recycler but I have gotten some cool stuff. He gave me a bunch of these and they all work but I have no idea what they are good for.
