Faulguy1, I am trying to be helpful, not overly critical. It is time for you to start making some of these calls for yourself. This forum is to help you learn to grade for yourself, not have us personally look at every board you acquire. You should have noticed by now, what it takes to make a motherboard. Everything else is either lower than MB or Higher.
Go back and reread the qualifications for the various classes. Then, sort all your unidentified boards into piles of boards that look almost identical. One added component or one component less generally will not change the classification, provided the essentials are there. (The exception might be gold capped chip board, where apparently one chip in a field of 50 qualifies it)
By rough calculation, you have posted in excess of 600 boards recently, and when I compare at random, it appears that the boards in question in # 73 are practically indistinguishable from those in post 22 and 37 and 51 (random posts picked without examination for implying similarity) There are some easy to see elements that set the basic classes: gold pin connectors, IC chip load, heavy transformers and large capacitors, connector slots, brown/green board color, socketed CPU's, etc.
If you have been sorting and boxing the boards that have already been identified, may I suggest you pick up a board, hold it over each box already sorted, and simply drop it on the box/pile that it most closely resembles.
In your defense, I will admit that in the beginning, when faced with sorting hundreds of boards, they do all look alike, until you learn the basic rules. Just think of it as working a jigsaw puzzle: shape, colors, edges (edge connectors) features of the design, special items that catch your attention, and pretty soon, you will just "know". The crew at Boardsort can unpack and verify my boards almost as fast as I can unload the boxes from my van. And, let me assure you, they DO NOT go ballistic over an occasional board in the wrong classification. In fact, often a board will go into a higher class because they see a valuable component that I missed seeing in my sorting.
Rant over: each of us scrappers wish we had your problem of identifying so many boards. Most of us started getting a few boards now and then, and had the luxury of time to think about each board. But, it will get done. Soon you will have your system down pat, and will learn what equipment contains what class of boards. Hang in there, big money is coming your way soon!
