Let’s look at my thought process for grading hard cases
My assumption is the ISA sockets are tin. As is normal.
Nickel in the memory sockets and for pins.
Some gold pin connectors.
At least peripheral. Definitely not backplane.
So a motherboard? Well there’s no bridge chip. No cpu socket. And a reduced I/o port count. But we have the plastic 486 package and a VIA controller.
It looks like we have a triple layer board. That less than the standard 4 layer motherboard. A reduced architecture x86. And no bridge.
I’m calling peripheral here.
So it’s a motherboard from an 80s Tandy tower. I would have sold it on eBay but there is literally nothing to go off of I spent hours researching various numbers on the board as well as the tower itself to no luck. Everything in that assumption was pretty much spot on. However I don’t know about the layering nor how to tell. The main thing that left me with no idea what to put it as was the cpu soldered onto the board.
