how would I classify these boards? leaning toward Slot board but can't remember where they came from.

I just sold a MB just like the one you have marked as ident2 on eBay for $150.00. Might want to research that one my friend. ;)

That would be a significant improvement upon anything boardsort could give me.
Much appreciated advice.

Since I obviously don't know what I have here, what is it?

I am not 100% sure exactly what this board is. It was manufactured a few years before the board I sold on eBay. The one I sold was an IBM 286 motherboard. This one while having many similarity's is a bit different. But I am sure it has value that would be close to the one I sold. I apologize that I couldn't be more helpful. I can tell you that if you do your research and find out exactly what it is, it will be worth it. Good luck my friend.
