Junk? (TT257)

I don't have a junk drawer, I have what our children refer to as a tidy up mode and a collection of useful artefacts from the history of technology.
Clearly - the interpretation of useful does vary significantly from one person to another  :-)

I'm sure many of us will remember the halcyon days of floppy disks!

Thanks to MaryElizaR for hosting tiny Tuesday.
