That made me curious. How is the floppy drive attached to the PC?

I haven't seen a FDD controller in a new motherboard in a very long time. I use GreaseWeazle[0] for my floppy needs.

The demo is about 500kB at the moment. We're hoping to fit the final version onto a single 360kB floppy but didn't quite get that working in time for the party. A 3.5" floppy should work fine.
