Re: For old SCSI, find a musician
If you want to use an old sampler/synth and the floppy drive has died, I can thoroughly recommend the HxC floppy to SD card emulator : https://hxc2001.com/.
Alternatively on the cheaper end, buy a Gotex emulator followed by the revised HxC firmware.
For narrow scsi, there's SCSI2SD. Above that, there's Acard, at a considerably higher price.
