[Coco] Preserving old CoCo diskettes...

My problem:

I have HUNDREDS of floppy disks from my CoCo. Some are standard 35-track, some are 40 track, and some are OS-9.

I want to get these all backed up, but things like HDB-DOS only deal with 35-track disks, so I have never been able to back up my data (including things like hidden DOS commands to set up 40 tracks, 6ms, etc.).

So, a few years ago, I wrote software to write sectors across a serial port (under OS-9) and would insert a disk and just stream the disk to the other side, where it would be written out as a raw disk image of sectors. (I think I actually used this to transfer an entire 128MB hard drive over!)

Someone has bound to have already faced this and worked up a better solution.

Anyone have suggestions? Hooking a 5 1/4" drive up to a computer is not an option. I'm running Macs and haven't had anything with a floppy disk on it since 1998 :-)
