Wow, you're not kidding saying that it's cursed. I thought it would adapt a socket to the BGA pads, but it looks like the pins of the replacement CPU just sit naked on the interposer.
I think Pentium 3 sockets were through-hole, so to use one they would have had to fit two different footprints on the bottom side of the interposer without any overlap. It might not have been physically possible.
