It's NOS, in original plastic wrap (which I
don't want to open, so I
can't tell you what's in it, but I suspect manuals and 8" floppies)
Someone pointed out to me that it's probably actually 5.25" floppies; the
original PC did come with 5.25's. The box size just looked the same as the 8"
floppy box, is why I assumed 8".
Like I said, I'm reluctant to unseal the box to confirm it's definitely
5.25", though.
