For information, the reference SFRC922D is printed on the board.

The Gotek seems to be often delivered without some of the required pins, so you might have to remove the board from its shell and had some. As I don’t have an USB-TTL adapter, I had do do it over USB. The first FlashFloppy installation has to be done either by serial or USB link to a PC host (as explain on this wiki page). Let’s go the open-source way ! This limitation seems to be irrelevant with the FlashFloppy firmware ! Yummy ! This model is the SFR1M44-U100K and does not seem to be able to read 720K floppies (the picture below is a capture from the owner’s manual). The MC-50 was complaining differently : “Error22 DISK I/O See owner’s manual”.

This page was written as a documentation for myself but could, maybe, be useful for others. I was really happy to discover this alternate open-source firmware ! As you will see later, It was definitely a good move ! Why ? Because it was not expensive, black and listed as being compatible with FlashFloppy. I bought a SFR1M44-U100K Gotek floppy emulator. After some years and a quick research, I decided that it was time to get this baby back to life.
