Some day somebody will need it
I put all my old tech out on the sidewalk. When the day comes that it's needed, somebody else can dig it out of their closet.
The trick is, of course, to dump everything related at once. Dump the floppy drive after the floppies are copied. Dump the USB 1 cables and the USB 1 devices together. It guarantees I won't be the one needing the legacy tech back.
