I have been using a generic floppy-usb converter several years in my old Yamaha PSR 1000. Your KB is PSR 550?. 8 GB usb apparently is
a waste as you use only 100x 1.44 MB (144 MB)for 100 floppies.
At present, there is not another one at less 8 GB, except some old devices for 2 or 4 GB.
On the other hand, this device is only for the emulator. V120_SFD software run i n Windows XP, 7, 8.1 & 10. Pardon for my broken English.
Best regards.
