Hello, I'm looking for a Voltage Regulator Module (VRM) for the 2nd Pentium Pro processor of the newly acquired IBM Personal Computer 365
Nowhere on the internet do I find the exact model to look for at least on Ebay or I don't know where.
Any help, information on this board is welcome.
Attaching photos.

You know what, I think it’s about time we made a (easy) DIY way to address this. There are a lot of motherboards out there with this header.
Can you upload the pinout of this, and the socket 7 header and I’ll make a pcb for tapping it. I believe the socket 8 and 7 header may be different. There is supposed to be a builders guide or a spec sheet for this connector somewhere, but I am not hone right now,
Edit: I see someone found the pentium pro guide sheet
anyway, my thought is to combine the pins into pads and make it easy to tap and run it off of the regulator of your choice. Similar to what we have done with the socket 5/7/ss7 tweaker and the socket 1/2/3 tweaker.
Something I ran into on designing the socket 5/7 tweaker is trying to make your own regulator has a huge Bill Of Materials. And requires significant soldering skill to assemble.
Something that can be solved by simply making a device for tapping it, not powering it. And use simple cheap off the shelf power supplies in line on the power cable.
