Here's the github for the Fujinet HW.
https://github.com/FujiNetWIFI/fujinet-hardware
It describes the cable necessary for making the connection to the dragon's parallel port, same as the existing drivewire solutions for dragon. The difference here is that the other solutions will go to an inverter, or an inverter and maybe a USB-serial adapter for connection to a PC usb port. On the current plan, we invert the serial port lines on the fujinet adapters's esp32 module. I will add that the current ROM image that's up there on the Fujinet hardware is not the one that I'm using, I have added the standard DW42-2515FULL.ZIP from the DOSPlus thread here on the dragon archive.
The current HW implementation uses that bitbanger port, but we have another parallel project underway using a raspberry pi pico to implement a both a rom emulator and a becker port communication port over to the esp32 fujinet module... this will obsolete the current bitbanger implementation, but for people that have an existing serial Fujinet for coco they can change the cable and get something that will be compatible with their Dragon 32, Dragon 64 or Tano Dragon.
The big purpose now for implementing this on the bitbanger HW for dragon is mostly to get the rest of the dragon for Fujinet implemented, which will all transparently move over to the new HW implementation.
The new pico based HW implementation is likely ready for adoption by this summer 2025, barring unforseen circumstances. So, thats pretty soon. For a bit more about that, checkout this link:

On the coconation talk from yesterday (
https://www.youtube.com/live/pPl14VtzT_ ... F27W&t=780), I demonstrated the early state of the dragon implementation with this bitbanger cable implementation. I should be getting the rest of this ironed out in the next few weeks. I have already improved the performance a bit.
If you have any questions about dragon Fujinet, I'll be checking here frequently, or you can ask in the Fujinet discord's coco section, or the Coco discord's Fujinet section.
Thanks,
