You have to associate to the Spanish web page to talk with them. Probably they accept to make one more for you. They don't profit on the project.

But that clone is only an EXDOS card, nothing more. Pear plans are more long term but also with full equipment. Surely  more expensive because they are more complex, but he charge very little for his efforts...

That sounds very good...

Soon you will have options for everybody.

Deputy for which you need it, labels made by me, for the ExDOS controller and the Basic cartridge.

Something like that.
EXDOS controller, 1MB of RAM, 512KB Flash and built-in FDD emulator drive with display (based on Gotek).
This is a preliminary draft and not yet counted the cost.
Recently, I have little time, so possible production time, it's probably early next year.

A few questions before I continued to work.
I used 8 MHz clock signal from the connector Enterprise.
Is it better to equip the card with its own generator ?

I also think about bridge-through connector on the right side, you can connect additional cards, but then probably the PCB will have to be 4-layers, which is more expensive.
Necessary ?

Your work is admirable, but the screen makes me jump tears ......
am very purist .......

My question: why is it important to use floppy interface and floppy emulator hw between the Enterprise and the mass storage?

Why is floppy needed at all?
On other computers (CPC, Spectrum +3, Amiga, Atari ST, etc) lots of floppy oriented programs exist which only run from floppy, because they handle the disks directly. But on the Enterprise the programs use EXOS/EXDOS file system, not caring about the hw level of storage.
You can easily expand the EXDOS with storage drivers. I think the easiest solution would be to use CF cards, because these have a native 8 bit interface, then don't need any complex hw.

We prefer the FlexiBridge, IDE-CF and RAM-Flash-Clock cards are welcome
