Legacy Device
Brings back memories of a legacy pre-USB device with similar consequence.
Made by chopping all the red stuff off the top of matches.. then dismantling a 3.5in floppy.. nail varnishing all the red gear onto the disk itself, then reconstructing.
Heard rumours that this trashed a drive once inserted, but never built one to test as my only machine at the time was an Amiga :-D
