Old 486 era motherboard, I’ve tried searching the various chips and identity marks on the motherboard but no joy.
Additionally can anyone tell me what CPU this supports?

486 dx2 socket, also says 486DX on the bios chip, not sure about the make/model, fit a cpu and see if it posts, it should give you some info on screen.
Something from Pine technology zoo

Thanks for the replies, seems odd that there a location that looks like it was for a socket but there’s nothing there and it says 486SX whereas the socket itself says 80487SX.

It's for variants of the board that come with a 486SX soldered in that empty location which you can later upgrade by installing a 487 in the socket, which is just a 486DX that disables the soldered CPU and takes over. Intel just made the upgrade process needlessly convoluted.
In your case, since there is no soldered CPU, it just acts as a regular 486 socket.

Yeap! 100%

You are a star, thanks so much for the explanation!
486DX with 33MHz bus and 5v voltage only
