Here are the two cards:
I think they're both graphics cards. They both have DB15 ports, and the smaller one has what I think may be a
BNC video output, too. I had a PC monitor with three of those on the back, back in the 90s, for RGB.
The smaller card is Apple branded, presumably the stock graphics card, and took the brunt of the liquid damage that took such a toll on this system.
The bigger card is in much better shape. It's a Formac ProNitron 80.21 B V1.1 with a ProMem memory expansion daughterboard.
The damage on this one is limited to this:

Something I should point out to everyone who's asking: this machine IS NOT MINE. It belongs to a local museum. As it's obviously way beyond easy repair, my advice to them is to part it out rather than to keep it. They're still to decide on that. If they do let it go, I’m only really interested in the ROM myself, for my SE/30.
IIfx RAM really doesn't work in an SE/30? Why is that, anyone know?
