Hi! I have several boards that I would like to be identified.I think that these larger boards are Low Grade Telecom. The smaller black ones might be considered slot processors or gold finger boards.

I know that these came from a telecom cabinet (just scrapped out some old nortel equipment myself), but they are not telco boards.
I am assuming that I am looking at one side of several different boards, not front and back.
For img 4996 Too much heavy junk in those transformers. The shear quantity makes me think mid-grade, but maybe low peripheral. Once removed you definitely have a high peripheral board, maybe low telco. Low telco is a confusing class to me based on what Chris has said in the video and his as well as Lostinlodos' responses to posts. I clean all my high telco, so if it can't be cleaned to clearly high telco, I assume it is high peripheral or lower.
Img 4998 pretty solid high peripheral as long as those ceramic plates have mlccs or chips on them.
img 4997 high peripheral
img 5001 definitely could go as GFC without bracket. They don't look like the slot processors that I have seen, but sure do look like they are some sort of CPU. I was half expecting to find an Apple logo on them, Apple CPUs are weird, but don't see it anywhere. Maybe someone else with chime in with an ID.

5001 are laptop graphics cards, as long as there's gold fingers (some don't have that) it's clean gold finger card

Out of curiousity. The pictured board. IMG 4998. I would cut one side of the ceramic plates(the hybrid circuits) gently bend it up and see what is underneath the ceramic. You might be surprised. I am only mentioning this since this is a telecommunication board. There may be a coating of gold diffused underneath. The gold would contrbute to the hybrid circuit's stability. With that said. You may want to rethink whether to harvest those ceramics.
If you do take a "look see". Let us post members know what happened.
