Thank You board identity please Thanks

I would think Peripheral High Grade at least.

Thought of a question for myself! If the board is PHG would it be best to pop out the socketed ICs and sell separately?

Hhmm , at the end of one side gold plated pins, have 2
Of them, I think they came off a boat, was with other boat equipment only assume,

The board is made by APC so I would assume some kind of UPS (uninterruptable power supply).

Interesting cool thanks, once was a boat mechanic, besides the point. One of the ends (larger size) gold plated pins, Thanks have 2 of theses

I worked on boats in the oil industry back in the early 90s. That is when dynamic positioning first came out and there were more computers on board to help with the GPS systems. Power on a boat is always fluctuating because it comes from a generator so UPSs are required for most computer equipment.
