I've got some information for you, which you might find interesting:
1.) It doesn't need a 400k disk to run. I've got it on an 800k disk for my Mac Classic. I took an HD disk and put tape over the hole.
2.) You don't have to just "come across" a 400k disk. You can make them any day you want. Take a double-sided disk, or even an HD disk and put tape over the hole. Then when initializing the disk, hold down the option key. You should get a dialog box asking if you want the disk to be one-sided or two-sided. Pick whichever one is most fitting to your desires.
