I have rather strange 80286 mb. It’s large (almost 40 x 40 cm), it has discrete logic, and sticker «1990» at amibios chip.
For me it looks weird — chipset on discrete logic instead of ICs in 1990?
Anyway, I could not identify this mb, no name, no p/n.

Maybe you could help? (fotos attached)
Would be grateful for any advice.

Thanks in advance!

Welcome to Vogons 😀

The PAxxx part code suggests it might be from Wearnes, similar to these https://theretroweb.com/motherboards/?manufac … 19&showImages=1

If You could post a picture that has not been taken with sony ericsson K750, maybe i could help also 😀
Please, make a picture with decent camera, where can we see chipset, and maybe we could help.

Hello! Unfotunatelly I don't have hi-res fotos at hand (this mb is stored in parent's house).
But I have some with more or less visible chips.

Many thanks! Will look for Wearens. But never heard before of such manufacturer.
