OK. I have about 500 DEC Ranibow floppy images that I've ripped over the
years.
I also have a number of .td0 images as well as other oddballs.
Other than Lotus 123 needing to have funky sectors on one of its bigger
tracks for copy protection, I think having the raw images suffice.

OK. I have just read in a bunch of Rainbow disks. Most of them read fine on
the first, second or third try. Some have a sector or three amiss (I've not
yet checked to see if those sectors are mapped to the filesystem or not).
Some appear to be 'unformatted' though sometimes they read with errors.
