At the other end of the age scale... My pal Fran
wondered where a few
of his CDs had gone to, until he opened his PC to change a card, and
found a stack of them. His four-year old son had sometimes "missed"
the CD-ROM drive slot, and inserted the CDs in the gap between the
CD-ROM and the floppy.
On Mac IIs (and similar machines) with one floppy drive, the blanking
plate for the other floppy slot is almost almost missing. It was common
to find a pile of floppies on the drive chassis behind that slot....
