Here is my motherboard in my Apple II, I wasn't able to find the part number, maybe its under the keyboard part. My board has different slots, they have a little flange at the end opposed to be straight like the others.

I am not sure if one board would be better than the other, if you guys could tell me what board or if both boards would work to swap chips between. I would have to buy one of the boards, the first board I could get a lot cheaper than the second. Thanks
