I've got the set all ready. Give me a mailing address, and I'll get them on their way.
Oh, and Disk Copy 6.3.3 is perfectly happy to read and write disk images to and from any Mac floppy. I have successfully read and written a 400 KB MFS disk using 6.3.3 on a beige G3 running Mac OS 9.2.2. (Even though Mac OS 9 can't natively read 400K disks!) Disk Copy makes the image, then spits the disk out. If you try to MOUNT the resulting disk image in OS 9, it fails, though. But a disk written that way mounts just fine on my System 6 machine.
Of course, if all you have is the 128k and the Plus, that doesn't really help you.
