I use this card as a floppy/disk controller in a PC/AT that's used solely for imaging.
The controller is connected to two Seagate ST-2502N (442MB) hard drives running MS-DOS
6.22. Works like a champ. Cables are readily available on eBay but since they're
regular 50-pin IDC connectors, you can DIY if needed -- connectors are readily available.

Do you have (and can you post) the MS-DOS drivers for that card? I
also run one in my floppy imager machine, which dual-boots btw. MS-DOS
and some later Linux. Having SCSI for at least one of the OSes would
be nice.
I could also switch the other partition over to FreeBSD, as Warner L suggested.

For that card, no drivers are needed for the hard drives. The on-board ROM is an Int13
wedge.
Regarding using any other devices like a ZIP drive, CD or a floptical, not sure if those
need drivers. ZIP definitely needed a DOS driver. The CD did as well (In both config.sys
and autoexec) but the ROM may have CDROM extensions already to enable booting from CD.
Never tried it with that card though.?

Ahh I didn't realize it was just the EZSCSI disk. Grabbed it just in
case, as I don't know which version(s) I have.

FreeBSD supports it with the aic driver.

A few SCSI floppy drives existed, but they were never very common.
Only SCSI floppy that I remember having was a "Floptical" (20MB), that
also handled 1.4M
Or, are you suggesting putting together an imaging machine that also
handles HDD, CD-ROM, some tape cartridges, etc.?

Correct. Two key components in short supply when you have 100001
classiccmp projects are space and motivation, so if I can dd an old
hard drive/Jaz cart/etc from the same machine where I'm reading in
floppies, all the better.

Most "real" SCSI drives were basically bolt-on adapter affairs to a
traditional floppy interface. You can, for example, occasionally find
Teac FD235S drives for sale--and if you look, it's basically a
SCSI-to-floppy adapter bolted onto a regular FD235.
There were also some SMS/OMTI cards that served the same
purpose--floopy-to-SCSI.

No, SUN always used standard floppy controllers. But HP and DEC used them,
although it was not very common. The floppy drives are standard TEAC
FD-235HF with an additional SCSI floppy controller board.

There is a SCSI floppy drive branded with Tadpole, I think.

I often have a 1522A in my disk imaging machine. Linux supports it, which
means I can use `ddrescue` with it. It'll also talk to a lot of
older/slower drives that my 2940UW doesn't like (e.g. very old DEC drives
from VAXen, it does better with some old tape drives
than the 2940UW). It's
slow, but I've also found that it's less likely
to cause a kernel panic if
you're working on a disk that is very near the end of its life. I suspect
that's due to being a PIO device.
Thanks,
Jonathan
