I've got at least three boxes of NOS Dysan disks with both of those index

The question I have is how did a contemporary
system deal with the
combination of a disk with both index windows and a drive with both index
sensors?
They didn't deal with it at all. It didn't work. No normal 8-inch floppy
disks have both index holes in the jacket. If you convert a disk from SS to
DS, or vice versa, by punching the other index hole in the jacket, you have
to cover the original, unless you're going to use it in a drive that has
only one index sensor (typically an SS drive).
