Hey, Guys,

After couple of unsuccessful builds for 486 system, I finally decided to order a brand new 486 motherboard. I found couple of places here in Bulgaria that are ready to print the board for couple of bucks, but unfortunately. I did not manage to find any CAD schematics of any of the 486 models.

Any websites or schematics are more that welcome, so I can provide the manufacturer with then and print nice new motherboards, fresh from the oven 😀

As always, thank you for your help.

For a whole one-off motherboard you'd be looking at EXPENSIVE. Minimum 4-layer, controlled impedance, etc.

I honestly doubt you can even find PCB art for a 486 motherboard anywhere outside the engineering archives of motherboard and/or chipset manufacturers, sorry to disappoint you. Finding a new-old-stock or just secondhand motherboard would be far easier and cheaper, even if it might take longer.

Yeap, I know it is going to be expensive. But I did not have any luck findind a proper MB so far, and I got sick of looking.
So, as a last resort if someone has an info, it will be much appreciated.
