Floppy emulator with flash media

Hello Steve,

Would you by any chance accept to ship some of those databooks away, instead of binning them? I'm always looking for data on some old CPUs I've got here, so you may well have some books that would be useful here...

Thanks! Regards, D.

PS: I tried to send you a direct email -- it bounced back with a cryptic Deferred: 451 Temporary failure, please try again later.

Ah. I'm afraid you're slightly too late. We've already bagged up all the books for disposal. Sorry.

If I get the chance to sort through them again, I will, but I can't guarantee it. We're now very short of time.

Yes, that's normal and benign. The fivetrees servers operate greylisting as an antispam measure:

But you shouldn't see bounces - your mailserver should quietly retry and will succeed after an hour or so. Unless you're doing stuff manually, of course, and not using a well-behaved mailserver. A bit like a spammer ;).

Ah I see. I can understand that: saturday is two days away!

No problem.

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!

Thanks and regards, D.

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.

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.

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

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

but it is only capable of reading from a virtual floppy, not writing t it.

Please, if you already have a working solution, tell me about it.

Thanks, David

A while ago in a similar thread someone posted this one:

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.

Hello. I do not know what the initial question was or the application Here:

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 (:-) Bu

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.

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.
