Generally speaking, all the sockets and chips around the battery need to be removed (you will find many more surprises under them) and then you need to measure continuity and fix all the traces that are cut. Unless there is hidden damage to inner layers, if this board has inner layers at all, it's not something that can't be fixed.

But in practice it's not a trivial repair and you wrote that you've never worked on such thing, so at this point I'm not sure how you plan to proceed?

One could also check the datasheets and try to connect 1 or 2 simm sockets or modern ram ics directly to the board, effectively skip the sockets entirely.

Friends, can you pls suggest me what type of XT Motherboard I own? (pic above)

1IBM 5150/5155/5160/5162/5170 etc.

That is not an IBM board.

any equivalent or similar?

Well if I didn't know better I'd say it's an XT clone of some kind but that looks like a 286 socket. Was that a 286 CPU that came out of it?

That board is missing all the typical XT board chips (8259 PIC, 8237 DMA controller, 8253 timer), so the chip in the "286-like socket" likely is an XT-on-a-chip, comparable to the FE2010A.

I removed few chips from the motherboard for cleaning purposes.
Here are few pics -

V20

This is the current status of the XT motherboard after removing the memory sockets.
Pls give your recommendations, it helps a lot and guide me.
