I just got an Ensoniq Mirage.. the drive would not read my OS disk, so i dug out a blank, cheapo Gotek and flashed Flashfloppy to be my drive.
GOTEK has to be model SFRM72‑FU‑DL AKA the 720k model
After i got all my files together, i added these jumpers that allowed me to flash the Gotek
Please remember that once the flashing procedure is over, you’ll have to desolder these jumpers to use the Gotek
After the flash procedure has finished, leave only a single jumper at SO
Connect to the board, according to this picture (please note red stripe position..)
Mount using the screws located underneath the Mirage like so (they are a bit narrow for the Mirage screws so make sure you slack the gotek holes a bit)
