What do you guys think? I would say High peripheral, but the fingers are throwing me. Could I get gold finger cards?

Any other identifying info on those silver boxes? I always get nervous seeing something like that because of mercury switches. I don't think they are in this case but more info is always helpful.

If the boxes aren't mercury, high peripheral.

I don't think chat gpt got it quite right. The limited info on top points to frequency mixers. This is why I asked if there was more info on the component. But I also like learning new things and I can't touch it to turn it and see the side ¯\_(ツ)_/¯
