I recently went with a floppy disk box from our basement to a friend who still has real hardware set up.
In this box we found among other things a floppy disk which caused trouble with Amiga Inc 15 years ago, in 2006.
The homemade Kickstart3.9 which boots on the A1000.
No backup ... and big luck ... no read errors.
