WTB SCSI Floppy Drives

Does anyone have any SCSI floppy drives of any kind?

I have an external enclosure that contains (so far) a tape drive, ZIP drive, JAZ drive, LS-120 drive, and a DVD/CD drive.

It would be great if I could get floppies to cover all the formats - not sure if 5.25 SCSI floppies ever existed?

I seem to remember a Combo 3.5/5.25 drive from way back - would love to get one of those, even with a standard floppy interface.
 
5-1/4" SCSI drives did exist. I have one. If I run across it, I'll let you know, but it may be a while.
 
I have not seen a SCSI floppy disk for almost ten years.

5.25" SCSI floppy was an option in the earlier Silicon Graphics machines. Never seen it personally though.

That's great - the 'project' has been hanging around for ages, so time is not a problem :)

Me neither - last seen on a UNIX workstation around 1995. Has a stack of 3.5's back then - wish I'd kept a few!
 
Yep. Mine is a Teac, and it has a SCSI-floppy adapter board on the mounting frame.

I think my drive came from a Tektronix machine. I used it with my Amiga.

Phil: Would the SCSI-floppy board be of use to you (you could use any 5-1/4" drive with it)? I may have one that came from a 3-1/2" drive, that I can find sooner than the other drive.
 
One reason that SCSI floppies aren't as useful as ordinary legacy floppies is that SCSI, by its very nature is oriented toward logical block (LBA) addressing and pretty much assumes that one track on a floppy looks like the next. Getting "interesting" formats is difficult and sometimes impossible. E.g., LS120 drives and USB floppies.

Wow - I don't need it that much!

Yes it certainly would - but if it came from a 3.5" drive, will it work with the 5.25" - IE how would it identify itself to the host? In any case, a 3.5" SCSI drive would definitely be useful!
 
You could also just look for a DynaFile. It's a two drive SCSI box that supported low and high density floppy drives. Was designed for macs but apparently you could make it worth with other machines too. You can kill two birds with one stone.

I wish! A quick google suggests these are as rare as hen's teeth - and I suspect if one ever came up on ebay it would cost more than the rest of my system! A pity - as it looks like it would be perfect.
 
ISTR some OMTI controllers that could do floppy-to-SCSI conversion. I suspect that rolling your own wouldn't be too much of a big deal. After all USB floppy controllers exist and use a similar logical (i.e. command set) protocol.

Did Rancho ever produce one? I have a Rancho floppy-to-parallel board, so it would have been right up their alley...

Thought about trying to create something - are you suggesting a SCSI to USB bridge? USB floppy controllers do indeed exist - but only 3.5" versions. Electrically, they are compatible with 5.25 mechanisms, but the on-board firmware that talks to the drive will only do the formats it's programmed for - IE 3.5" ones. If I attach a 5.25 mech, I will get 720K/1.44M 5.25" disks (assuming I can 'divorce' the USB bridge from the drive).

If you discount things like Kryoflux, I know of only 1 (deviceside), and it's read only.

Cant find any interfaces that convert SCSI to Floppy.
 
As far as I know those Teac SCSI adapter boards can work with quite a number of different floppy drives. They have lots of jumpers and are highly configurable. Infact, I found the pdf manual online at some point. Not sure if I still have it.
 
I was thinking of an MCU+floppy controller combo, but with a SCSI interface; akin to the Microsolutions Backpack drive. On the other hand, it might be simpler to find a Teac SCSI adapter.
