that works too.
; 2021-02-05 : upgrade the gw software to version 0.22. For some reason, the setup.sh or setup.py is missing from the release .zip file, so I'll have to install the software manually:

now check that the software works
<pre>

Usage: ./gw [action] [-h] ...
  -h, --help  Show help message for specified action

  write      Write a disk from the specified image file.
  erase      Erase a disk.
  seek        Seek to the specified cylinder.
  delays      Display (and optionally modify) Greaseweazle drive-delay parameters.
  update      Update the Greaseweazle device firmware to current version.
  pin        Change the setting of a user-modifiable interface pin.
  reset      Reset the Greaseweazle device to power-on default state.

next, update the firmware (put a jumper on the gnd and dclk pins at the end of the Blue Pill, then connect the gw hardware to usb)
<pre>

looks ok. Next, try to convert the flux file to img

it does. That is very useful. I also verified that I can extract files from the image - it works. Conclusion: the Greaseweazle hardware and reading prorgam (gw.py) is ok, but Disk-Utilities have trouble with (at least one example of) ND format 0b.

T0.0-76.0: IBM-FM DD (8 512-byte sectors, 4096 bytes)

Note: the 512-byte sectors doesn't look right, they should be 1024-byte sectors.

Finally, check the image with ndfs

looks good to me. I have also tested extraction of files from the image

upgrade the gw software to version 0.22. For some reason, the setup.sh or setup.py is missing from the release .zip file, so I'll have to install the software manually:

I remembered that FluxEngine now understands SCP format. Let me see if it can do anything to the scp file from a ND format 0b floppy

first - convert to flux

looks ok. Next, try to convert the flux file to img

that worked nicely. Does ndfs agree?

it does. That is very useful. I also verified that I can extract files from the image - it works. Conclusion: the Greaseweazle hardware and reading prorgam (gw.py) is ok, but Disk-Utilities have trouble with (at least one example of) ND format 0b.

lots of warnings before the final confirmation - the program was able to understand the format. Test with ndfs

looks good - try to extract files

and the files are here

total 296

-rw-r--r-- 1 tingo tingo 184320 Sep 21  1987 s3-config-c00.prog

so that looks like it works.
