Hello,
Can anybody identify this 486 board? I'm looking for documentation and/or jumper settings.
I have a bunch of 486 CPUs, memory modules and cache chips that I can use to test it.

That Dallas Clock chip spells trouble.

If you mean the dead battery inside the Dallas chip - it's a non-issue to me 😉

Good lucky I look and nothing even close to it I look a lots motherboard layout not one was even close in data base in fact there is nothing on U.S. Technology or MG Product that most been a very short live manufacturer or got new name.
Not very helpful, but looks like somebody else has tried to ID this board in the past. Nothing else useful in that link except a similar board that may or may not be related.

PCs, Macs, old and new... too much stuff.
I would say to try removing the serial number sticker, in case there's a model number underneath.
Nothing underneath the sticker 😐

Grab a close shot on these jumpers in the corner.
Do you have a DX2 66 ? To test ?
The 2 blue jumpers near the simm sockets are "probably"
for the bus speed. Let say they are configured for 33MHZ.
What CPU's you have there ?
Since the this board is kinda modern 486 board i would say it's configured for 100 or 120MHz CPU.
