As an update. I found out that the Agfa works properly, and wthww was able to help me find the software for it! Unfortunately, the software is PPC-only, so right now it is running on a machine we have at the office, an old Beige G3/233 with 192mb of ram. Not the best ever, but it runs 9.2.whatever quite handily, and it's suitable for the task of moving photos around.

I'll post a bunch of the images either to my wiki, or to my flickr stream when I get an opportunity.
