Hello I'm new to the board sort scrap stuff. I don't know what any of the stuff that I have is for sure. A lot of it I think is CNC board but I've never done this before so I don't want to send something wrong and have it not be acceptable. If I post pictures here will someone tell me what it is. Note I do have a lot of the stuff laying around.. I hope I don't annoy you guys too much with a ton of pictures. I've just let it accumulate over time because I've heard that It can be worth money but never new where to send it or how to tell what it is. A few scrap yards I go to have tried to buy it off me me as "copper bearing" but only offered like $0.05 per pound or something stupid. I would greatly appreciate any and all help. Thank you so much!

You can post photos in the what is it category.

You also need to find a different yard. CBM starts around 15c nationally for heavy steel transfer motors and sealed transformers. (CBM 3 or 4)
Any yard offering less than 50% of the rate is ripping you off.

Here's a good place to start. Spend some time looking at other posts that have been verified and it will give you a better idea.

This is my first post.
What are the circut board category for these 3 boards?

Both as is are high peripheral

The first board, those ICs are socketed. I can’t zoom in enough but they look like second-party Intel transmission controller pairs: one for coding and one for memory/cup interrupt.

They are (usually) ceramic chips with silveride pins (tin in more recent years)
Those chips are Flat Pack Gold Tab (and may be upgraded)
Chris, and crew, may upgrade the chips on reception. So make sure when you send your tracking number you mention that the shipment contains ceramic chips needing class verification


I’ve never seen these pairs chips with gold pins but if they have them it’s AMD ceramic no metal.
