Hi!

Is this kind of Gotek supported by the HxC2001 firmware? This type doesn’t come with the 34 pin fdd header but an USB plug.

Thank you

Thank you.

And is there any remote possibility that it will ever be? The chipset seems the same.

Anyway, thanks for your great product!

Sure ? Which "chipset" is it ?

Why do you need this usb version ?

Look at the pictures. there are 2 "chipsets". I need the USB version for an HP Thin Client that I use as a retro-computer with MSDOS 6.22 and it lacks the FDD port.
The J3,J4, etc is exactly the same. In fact, I was able to "communicate" with the "Flash Loader Demostrator" from ST

Ok dual MCU. interesting beast !
But no the hxc firmware definitively don't support this.
But anyway are you sure that MSDOS can work with these USB drives ? This is emulated by the machine bios ?

What a pitty. Should be a perfect candidate for your firmware. Nothing can be done?

Lot of things can be done, but if this need some hundred of hours of work for just ~10 users ( 100 euros :D ), i think i prefer to do something else.
Here 2 firmwares are needed :
- One on the main MCU to handle the USB stick, which is more or less what is done on the current firmware.
- One on the secondary MCU to emulate the USB Floppy drive.
i bet that both MCUs are interconnected with an SPI link.

I have a question : Why do you want to change the original firmwares ?
If the answer is "to support special floppy formats", this is anyway not supported by the USB specification nor the machine BIOS so...
I am not sure about the "added value" of a custom firmware(s) here.

Yes. But the BIOS need to support the floppy drive over USB for this.
And when it does, you can generally just format an usb stick and install MSDOS 6.22 on it with all your software and boot from the stick. (see https://rufus.ie/)
That's why i am not sure that these floppy emulators are really needed here.

I see your point and if there’s a lot of work to do I wouldn’t do it either.

With your firmware I would be able to throw the disk images directly to the usb pendrive, organise the in folders, not to mention the easy of use with an oled screen... :D

Anyway, thank you for your helpful explanation and we can close this thread
