What is this board?

[mo_steelers]

I'm new to circuitry and have been relying on googling to figure out most things - but this one has me completely stumped.

Anybody know what it goes to?

For one, it looks like a VME bus card. See https://accusrc.com/product-National-Instruments-VXI1200FlexFrame-8420

the VXI1200 has 3 rows of 32 pins on the backplane connectors, this board has 2 rows of 16 pins in each connector. maybe something similar, but not for a VXI1200.
