G3 "Wings" Personality Card - what are the sockets for?

I had just popped open my G3 tower to replace the PRAM battery, and had to remove the "Personality Card" to get access to the battery holder. I took a quick peek, and noticed a lot of un-populated connectors. One looks like a PCI slot, the others appear to be custom.

Just wondering if anyone knows which devices/parts go into these slots, and what functionality they provide.

Shockingly, there isn't a good high-resolution photo of one in the internet, so I'm uploading some now...
