Which expansion card is this?

So I picked up 3 compacts from the side of the street in Arlington, MA yesterday. Rather I could say my girlfriend grudgingly picked them up for me. I found:

} A Mac Plus converted into a Mac 'o Lantern - would look very nice if the paint hadn't chipped, not sure what to do with it now.

:?: An SE - Boots to the flashing question mark/disk screen, which is disconcerting because it has a 20SC hard drive, and the hard drive blinks and you can hear it working. I only have 1.4mb disks at home, can my Classic format one to 800K?

:?: an SE/30 - Also boots to no OS screen, but has an expansion card that I cannot recognize! Perhaps someone can identify it:

That card is a video output for some kind of PC monitor.

Open the case and pull it out. I'm sure it has some sort of code that you can use to identify it with, or at least chips you can look up.

Are you sure that your SE is an early 800k model? The 20SC disk was available on 1.44Mb models, too.

A 1.44Mb disk can be formatted as 800k by taping over the square hole on the right side of the disk when viewed from the top. However, this doesn't always work, and if it does, it usually results in a decreased disk lifespan. But all you'd be out is a floppy disk, so it's not that big of a deal to experiment.

I'm not sure what that card is. I'd say a specialty serial card of some sort. But yeah, crack the Mac and try to find identifying features on the card itself.

Yeah, it clearly states on the back that it's an 800k model. I plan to open it, but it seems like I'm never going to find a screwdriver long enough to fit into the handle and turn the screws! I suppose I'll search around the internet and try to find something.

Tried a different disk, and got the boot image working on the SE/30. Wonderful little program.
