Writing SCSI 9-Track Mag Tapes from Windows/DOS

I think that the options are limited these days. As far as I can tell the Adaptech USB Exchange isn't supported past XP. I have no idea if it works as I don't have one to try. They also seem "Rare and Expensive"
You can get a machine with a traditional PCI slot and use an older Adaptec SCSI adaptor. (I keep a box of these and a machine with a PCI slot). You can get PCI-Express adaptors but the cheap ones won't fit in my desktop as it only has a PCI-Express X1 slot and most of the adaptors need an X4 slot... e.g.
and the X1 versions are expensive...
and these are both U320 standard so only Low Voltage Differential (LVD) devices will work and many older disks are 5V single ended...
... of course you can get converters but the price is high
So keep an old machine and pray it does not break.....
