FM Towns:Floppy Drive Emulators

Tower Models and the All-in-one models
All Tower models and U* models use a unique and semi-proprietary FDD that integrates the 5V power between the ground pins. Pins 7,9 and 11 are 5V. You can't fit a floppy emulator in a tower model as you need to create a custom adaptor. More research is being conducted on this.

Desktops
The EA and Pentium type desktop models have normal 3-mode Shugart floppy drives. So adding a gotek with custom firmware or an HXC floppy emulator is plug-and-play.

EXT FDD Port
The External Floppy Disk Drive port is a semi-proprietary SCSI-type port. Research is being conducted on it. It is possible to run a floppy emulator from it if you have:

However, it is very difficult to find them in the wild.
 * Fujitsu official external FD enclosure OR an FMR computer external FDD
 * Install the Floppy emulator in said enclosure
