Oh come on, it is obvious they just do not have it and want to design
the
thing if they see the cash.
When I got the inquiry I offered to build 100 at $450 each or a few
(4-5 units)
at $30k. This probably beats their price and my timing will probably
beat theirs (certainly if they - as I would - are also starting from
scratch,
which is most likely the case :-).
Actually I pointed the guy by whom I got the inquiry to them when I
saw
their anouncement (a few months later), I may ask him what he found
out
there.

Those looking for MMC/SD card floppy drive replacements are generally
people using machines with some computer which only has an FDD as
a transfer medium - for cutting shapes or whatever. Some of the FDDs
are only DD (not HD, 1.44M), try to find such a diskette. They use
HD diskettes which sometimes may work... (DD disks used to work
fine as HD ones, the reverse was not true IIRC - 20 or so years ago).
So there is no OEM market for that, customers are probably individual
only - and not that many.

I contacted them about that time. I did hear back asking for more
information about the application and haven't heard back from them since
I suggested I only wanted one or two. I think they mey be looking for
OEM only. Although why you would OEM that is a bit of a mystery to me,
adding MMC/SD seems easier.

Hello.
I do not know what the initial question was or the application
Here: www.thesvd.com
you can find a virtual disk for some old computers. Also it does not
use a flash card or so. But the nice thing is it connects to a PC so
you can use all kind of memory (:-)

A while ago in a similar thread someone posted this one:
http://www.datexeurope.com/emulator/DTX200en.htm
May be worth a check - I have no idea whether they really have it
etc. Since this question seems to come up every few months
(once I even got an inquiry on such a thing by someone who must have
thought the development costs were within his reach),
please let us know if you find something out about it.

I can see that the last post here is from last september.
Have you had any luck with this device yet?
I am looking for a solution for it too.
I have found a promising hardware here:
http://jeanfrancoisdelnero.free.fr/floppy_drive_emulator/index.html
but it is only capable of reading from a virtual floppy, not writing to
it.
Please, if you already have a working solution, tell me about it.
Thanks,
David

But it must have been an impressive piece of work, I can well
appreciate it!

It did support formatting. That's easier with ST-412; a floppy can be
FM or MFM encoded.

Now I see. Pretty much the same set of design goals I am looking at, but
at a higher speed. Did your gizmo also support disk formatting? This is
one part that may not translate easily between different media.

You don't seem to understand; the gizmo I made adapted an IDE drive
(which one can still buy) so that it would emulate an MFM hard drive
(ST-412).
It could be used to replace an old MFM drive, which you can NOT buy
anymore.

I understand now. But apparently my ISP's mail server isn't well-behaved, as
it had been trying for four hours before sending me what is actually a
notification, not a bounce, my mistake.
It seems that fate didn't allow me to have your books: had you received the
original message in time, there may have still been a chance that they would
not have been in the bags yet!
