How saying to the creator of the interface to take me in account in case of going in a production phase of the card.

Yep, cool!

What happened to Saint's one?, is it still being developed or has it been superseded by this one?

As far as I know, these are paralell projects with no cooperation.

Saint's one is an expansion port device, with ram (and maybe rom) expansion, too.

The hungarian one is a cartridge solution, with rom, and 8k special writeable memory, but no normal ram expansion.

I hope there is no superseeding or such, I would like to get some of Saint's devices, too.

Not fully true!
The Hungarian interface are the first working solution.

Then I suggested few technical details to Saint (for example the shared ROM/RAM segment for the SD driver), and I passed my EXDOS expansion code to Saint. He added own HW handling code to it. At the user level both will working same.

So then it would be great to have not one; but two mass storage devices for the Enterprise :)

I'm eager to see one of them fully working (the hungarian one seems pretty close to be 100% operational, isn't it?)

As far as I know, some of us already using one of the 1.0 version of the cards.

I did not hear any complaint, yet. But in this 1.0 form, the card is not available anymore.

They developed an other "Premium" version of the card, and the first batch of these "Premium" cards is in construction phase ...

Till now, I do not hear a person using the Premium version in practice. We wait them impatiently ... :)

My expansion is basically finished, I've just been lacking the time recently to get it all finalised and some units built. :roll:

Good to see the cartridge expansion!

I've decided to get on with it and try and get some built up -- hope to have a small batch (like 5 or so) ready for sale in a few weeks, then more to follow. Mostly it'll be waiting on components... :)

Okay, tell us when we can "sign in" or something,
or maybe Zozo will gather a "hungatian batch" when he arrives back from the mountains,
so tell us what are our options when those options are already available.
