Today I got a pallet of old telecom equipment. I am not real familiar with this type of board. I am sure there is value here, I am just not real sure how to grade them. I do know that some of them are really cool looking. I stand to get many more pallets of these types of equipment from these folks.
I have included some pictures of the boards.
The first 3 are all the same board from both sides and close up.
Thank you for any information provided.
