Does anyone know if a usb --> scsi adapter might allow me to connect an hp 9-track tape
drive (7980s) to a computer running windows-7?
Has anyone done it?
Any pointers (drivers etc)?
Thanks.

I believe they existed, long ago. USB1 ones were terribly terribly
slow. By the USB2 era, SCSI was disappearing, but they might exist.
USB3, forget it.
But I suspect that a device that old (we're talking
turn-of-the-century) won't have drivers for Win7. You *might* have a
chance of getting it working on 32-bit Win7.
E.g.

Note the supported OSes.
This looks more promising...

Speed is not a big issue (9-tracks aren't very fast to begin with)...but I'm not
sure what flavor of scsi that the 7980s has...I suspect single-ended, so would something
With ultra scsi work (is it backward compatible with single-ended)?
If drivers are an issue, might it work if I spun up a virtual machine under windows-7 that
ran an older os (either windows or linux)?...could the windows-7 machine just pass the
USB device to the vm (and the vm would have drivers for it), without the host OS needing
drivers?

In my experience - which is, admittedly, limited - SCSI (well,
parallel SCSI; I don't really consider SAS SCSI, even though it has a
very similar command set) is almost completely compatible. The
"almost" is differential - what is in retrospect called high-voltage
differential, that is, as opposed to LVD (low-voltage differential).
Except for HVD, my experience has been that you can pretty much plug
anything into anything, with adapters as necessary, and (with some
termination caveats) it'll Just Work. Often everything gets slowed
down to the speed of the slowest device on the bus, but it still
_works_.
I'm sure there are exceptions; I don't for a moment think I've met up
with every variation SCSI has. But part of the point of this note is
to provoke those familiar with them to mention them. :-)

I couldn't tell you about the 7980, but the OEM version, the 88780,
was available with multiple options including single-ended and
(high-voltage) differential. Most of the ones I've seen in surplus
were differential. Unfortunately that is NOT compatible with LVD
(low-voltage differential).
There used to be active adapters between single-ended and high-voltage
differential, but they were uncommon and expensive.

I have the RATOC U2SCX with 32 bit driver, and I think a 64 bit driver for
Win7.
But have only used from winXP.
I have used with HP DDS1 drive (don't recall number),
Tanberg SLR5,
Travan - Seagate STT320000N
I use under Cygwin the commands: mt and dd.
But also in slow process of rolling my own reading code.

Yes, sort of. I have a Xircom PortGear USB->SCSI adapter hooked up to
that exact drive right now, concidentally. Win7 does not have drivers
for the Xircom, but your average Linux distribution does -- and if you
run that distribution in a VM (for example, using VirtualBox) you can
forward the USB device from the host to the VM and use it there, which I
have done successfully to image disks and tapes. It's not the fastest
device, but it gets the job done and it's very convenient.
