I guess a all made in USA 486 is not possible, all those Taiwanese chips inside 😁

Well, according to the “Buy America act”
To be labeled “Made in USA” a product needs to have at least %50 parts made in USA.
These computers are also assembled in USA.

So while you can’t have a totally “Made in USA” 486 computer they are close.
Only the floppy drive I can not find Made in USA.
Everything else you can.

So I am testing computer that have the “Made in USA” label printed on them.

What I am testing is mainly the motherboard setup.
CPU, RAM, Cache, Video, Bus speed, etc.

I am looking for just 1 test that can test all these features and provide 1 combined score.
