Hello, i obtained this motherboard, is enough oxidized on one corner, have no idea it would work... :(
But if it worked, I want to ask to jumper and DIP switch setting.
It appears to be planted with 512 kilobytes of RAM

It looks like the Suntac JS-128A that I have. :-)

Thanks, it is probably dead, No sound, no video response. Those leaking batteries buries most of these motherboards...

Thats too bad, I have a similar board myself and it has always been a stable, reliable board that is quite fast for a 286. But from the amount of corrosion on your board in the picture, it may have destroyed some of the smaller traces.
