Cleaned/oiled/reassembled all the Bernina bits and it worked right away! The tab on the bobbin winder wasn't lining up with the bobbin, but I just bent it a little and now it's good. I didn't have to do anything to the timing because I was unable to remove the bit that holds the bobbin case, so I had to clean it in place as best I could.
The 2 needles it came with aren't flat shank or round shank, but a mostly round shank with a groove, which I'd never seen before. Aside from the groove they're the same size as DBX1 needles, which are easy to get. The industrial I use at my alterations job takes them, but I also had a pack of my own that I'd mistakenly bought while trying to find needles to fit my serger. The hole in the needle bar had a tiny little nubbin on the inside (for the needle shank groove) which was evidently made by sticking a small bit of wire through a hole drilled in from the outside. I sheared off the nubbin and now it fits DBX1's!
It came with 3 bobbins and I have some more bobbins I bought from a junk shop that might perhaps fit, but I haven't tested them yet. I also haven't got the drop feed to work (possibly because I wasn't doing it correctly) but those are problems for later when it has a power source.
The machine head was the easy part, and the treadle table will need a lot more work. The metal plate under the machine needs de-rusting, stripping, and repainting. The wood needs refinishing, and part of the veneer is chipped and has been filled extremely sloppily. The bottom drawer is so firmly stuck you'd think it was glued in place. Part of the cast iron treadle base has broken, and it's not one that's essential for running the machine, but I really would like to fix it too.
