I inadvertently acquired this 386sx motherboard, and noticed that it has two strange slots; they're longer than 16 bit ISA; in fact they look like double 8 bit ISA slots.
I also can't see where the CMOS battery goes on this motherboard.

Anyone have any ideas what kind of slots they might be?

They're usually for proprietary memory expansion boards.
Also the battery is built into the Dallas chip in the right lower corner of the board.

I/O, I/O,
It's off to disk I go,
With a bit and a byte
And a read and a write,
I/O, I/O
