Hello,
just saw that this USB Drive
USB FAT32 720KB SSD Floppy Drive Emulator For Machine Control
http://r.ebay.com/IzmFyK
was successfully used to replace the floppy drive in Yamaha SY99
synthesizers.
A handmade cable adapter was necessary though.
I wonder if anyone tried to use this to replace the floppy drive in a
Roland S330 or S550.
Thanks,
Franz
