Just out of curiosity, what are you using this board for? The IBM 5150 uses at least three different mother boards, 16K, 256k, and I *think* 512K soldered in RAM. Each is expandable to 640K with 3rd sourced RAM boards.
I should have (somewhere) at least one of each. I also have several 5150 complete units including keyboard (not so sure about the monitors.)

But it has to be IBM. Sent with Proton Mail secure email. I have one at Kennett Classic for sale, I think it's $20. I believe it's an original IBM, but it may be a close clone. Untested. b
