Dweller used his Amiga in the late 80s and early 90s. He has about 5000 3,5" diskettes from that period. He tried to archive the diskettes by hand, but that took too much time. Then he tried to build a automated device from LEGO, but that did not function very well. The most recent version works perfect, Dweller used an old diskette duplicator, a Kryoflux and a Arduino micro controller. He also added a digital photo camera to take a picture of each diskette label.
