I foud an old iPod Classic lying around. I knew I had it, but now I actually found it.
But the HDD was broken and slow and the battery rather done. I figured there must be something one could do to fix that.
It was loaded with music which I hope to be able to extract.
It also seems there are pleny of ways to upgrade and fix it: An iPod for 2022.
My iPod model
Upon closer inspection it seems to be an iPod Classic 5th Generation - Enhanced with 80 GB storage.
