If you need to run continuity checks between the 5v pin and the power, test pin 1 on the CPU (see below) with the 5v pin, and pins 1, 3 or 5 on the ribbon cable connector. The 26 pin FFC model runs on 5v, pins 1, 3 and 5 on the ribbon cable connector are power input rails (pin 1 is on the very left side of the FFC connector). I disconnected RB but kept the EEPROM alone on mine. Retaining the RB+EEPROM (used by the original firmware to.I don't even know what it does as this Gotek variant does not behave like normal Goteks, so formatting your drive into multiple segments of 1.44MB in size is not going to work).is purely up to you. Once it's removed the device will work just fine.

Just to confirm with the postings of - you do have to remove/disconnect resistors RA and RC for the device to get out of flash update mode. Mine has a revised logic board variant (SFRC2DA) that looks to be almost the same as the SFRC2D. Mine was used with an IBM slimline floppy drive enclosure (formerly occupied by a TEAC FD05HF) to allow oldschool ThinkPads (560E) to work off disk images and whatnot. Hi - fellow Flashfloppy user here with the SFR1M44-DU26. Any help on this would be greatly appreciated. I can see the LED inside of the USB drive and the ones on the emulator give feedback when I try to access the drive. The USB drive does however increment/decrement the virtual floppy disks when I press the front up/down buttons.

Also tried removing serial eprom - no difference. To this point I have tried every option in FF.CFG (placed in the root directory) with no success. Looking for some assistance in how others who successfully got this working and how you all prepared your USB drives and what image settings you used. I have tried a 1Gb and 2Gb stick formatted into (99) 1.4Mb disks. It just won't read my files (previous oscope screen captures while using the floppy drive) that I placed on the disk for testing. You can see in the pic that my oscope finds the drive ok and lists the directory screen. My scope constantly gives me a message to insert floppy disk, which leads me to believe that my USB stick is not properly formatted. I have successfully upgraded the firmware to FF and tried v3.9a and 2.13 with the same results. Only jumper in use is the S1 jumper on the rear header.
Currently have the RA, RB, & RC 0R resistors removed. I also have the SFR1M44-DU26 26 pin version and having trouble getting the oscope to recognize my USB stick.
