Keir Fraser’s Greaseweazle is a project for versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any diskette format can be captured and analyzed - PC, Amiga, Amstrad, PDP-11, many older electronic musical instruments, and industrial equipment. The Greaseweazle also supports writing to floppy disks. The design is fully open and comes with no license encumberment.
A companion code library, Disk-Utilities, converts between flux images and multiple, standardized floppy disk image file formats. These can then be used in hardware floppy emulators, like the Gotek or FlashFloppy, or as disk images in hundreds of pure software emulators.
Very inexpensive! $30us!
The FluxEngine is a very cheap USB floppy disk interface capable of reading and writing exotic non-PC floppy disk formats. It allows you to use a conventional PC drive to accept Amiga disks, CLV Macintosh disks, bizarre 128-sector CP/M disks, and other weird and bizarre formats. (Although not all of these are supported yet. I could really use samples.)
The hardware consists of a single, commodity part with a floppy drive connector soldered onto it. No ordering custom boards, no fiddly surface mount assembly, and no fuss: nineteen simpler solder joints and you’re done. You can make one for $15 (plus shipping).
I might even have the board it requires in my drawers someplace. It looks suspiciously familiar.
As I haven't found a good source on archiving your personal collection of Atari software on floppy disk, I documented my own progress, so others might benefit from it.
I started looking for methods to copy my floppies to a PC so that when my 1050(s) break down, I still have some of my source code, letters, games, etc. As I only have recent hardware in the form of Apple, PC (intel) 'antiques' - albeit almost 20 years younger than my atari's - laptops from Y2k or a little bit more recent and several 'embedded' stuff in the form of Arduino and Raspberry Pi's, I started this journey by looking into the various methods that are available to hook up one of the aforementioned devices to my Atari and 1050 setup so I could start archiving.
