Ebay link here). It's a floppy disk emulator for the Amiga that uses a USB drive instead of the obsolete floppy disks. I would have been happy copying files to empty floppy disks, but there currently isn't a solution for doing that with Windows 10. At least, not one that I know of. So the next best thing was to emulate the hardware.
You can remove the floppy disk drive of the Amiga and stick this thing in there, but then you lose access to the floppy drive. So I also purchased a cable to connect the emulator to the external floppy disk port on the back of the Amiga 500.
So I contacted people in the Commodore community to see if they had any insight. Of course they did, because the Commodore community is insanely cool. It turns out that the Amiga 500 can't detect an external drive with its internal drive also working. At least, not an emulator drive. I needed a physical switch to tell the computer to look at the external device as the primary device.

Using increasingly larger drill bits, I drilled a hole large enough to fit the switch.
There's more I'd like to do with the Commodore Amiga 500. It definitely needs a cleaning and retr0brighting, but I also hate the video adapter that came with it. It sticks out like six inches from the back of the computer and looks stupid. I'd like to find an HDMI solution, or at least some way of using fewer parts and cables.
Finding an NTSC Amiga computer was the hardest part of this project so far. The Amiga line were much more popular in Europe than the US, and they came out when PCs were starting to really take off. On top of the computer itself being very expensive, the components needed for the USB drive also weren't particularly cheap.
