You should read the post of ijsf again, no need to change the firmware of the drive to use this in a ST, and it works just fine.

Long story short, if you're willing to do a little hardware hack, this cheap little emulator works perfectly fine! And although HxC is a very nice project, if you just need the bare essentials for USB media exchange with your Atari, you're way off cheaper buying this one. As the GOTEK firmware can only properly read/convert 1.44MB formats, the 720KB yielded corrupted data, but to my surprise the 1.44MB images are working! st images with different formats which were then low-level copied (dd if=. I took the ST floppy image tools from Hatari, notably zip2st, and created some. So I assumed it was merely a matter of getting the right filesystem on the USB flash disk. As the MCU had easier access, I chose to connect its 16 MHz to the FDC's CLK and booted the Atari to find out it couldn't read, but it did format the USB flash drive that was connected to the GOTEK.
I desoldered the CLK pin 18 on the WD1772 FDC and found out I could source a steady 16 MHz clock from either the SHIFTER (U401, pin 52) or MCU (U400, pin 2). As some of you know, the WD1772 02-02 is "overclockable" from stock 8 MHz to 16 MHz (out-of-spec) and the double clock rate results in TOS 1.xx being able to actually read HD disks! Well, I did buy the 1.44MB version, and as my Atari 1040STFM shipped with the EPSON SMD-380 - which is a 720KB DD drive - I assumed it wasn't going to work, until I found out a little more about the floppy logic and the WD1772 Floppy Disk Controller that was used on the board. My Atari recognized the GOTEK without any problems, but unfortunately it couldn't read anything. The GOTEK has a couple of jumpers at the back that allows you to this (close S0 instead of S1, M0 is for Motor Select but can be kept open).
#Gotek usb floppy emulator Pc#
I went ahead and bought the cheapest 1.44MB HD version I could find (SFR1M44-U) for under $20 to try on my Atari 1040STFM (PAL, Dutch).įirst of all, as we all know the Atari doesn't do the IBM PC Drive Select hack, so any floppy drive must be configured with Drive Select A. 720k (DD) versions are currently costlier than 1.44MB (HD) versions, and contain a different firmware (the board is powered by a small ARM CPU + memory with a firmware that does the FM/MFM->USB logic conversion, pretty clever). I don't necessarily want to revive an old thread, but I did actually buy a GOTEK emulator and tried it anyway so I can tell you guys something about the compatibility.įirst of all, these GOTEK USB Floppy emulators come in different versions, with different firmwares and corresponding prices.
