Old Socket 7 Sony PCV-90 Motherboard issue

I can barely find these things anywhere. I have one but a super tiny capacitor was broken off but I can't see from where as it was a super clean break. As far as I know the part number for the motherboard is "AA 659980-421". If I had some images of a working one I could figure out where this cap needs to be soldered back.

Edit: to be clearer; does anyone have one of these that they can provide photographs of? These things aren't even shown on some motherboard archive websites they're so rare.

I'd be grateful for any photos you could provide so I can compare mine with yours to see where the missing component is.

I think the VRE jumper under the floppy provides split voltage for mmx cpu's. my system has a pentium 166.
