Why not ? Low-end SCSI controllers are pretty cheap nowadays -Quote:>We don't want to have to buy each machine a SCSI card.
you can get decent ones in the 30-50 $ range (e.g. the NCR810

slow and somewhat unreliable. DAT based backup devices are a bit
more expensive, but reliable - and IMHO that's what you want from
a backup device.
If DAT/SCSI is too expensive for you, I'm afraid you're stuck with
parallel-port devices. In that case you should look closely at
what devices are supported at all in Linux - the latest ftape
driver has some new parallel-port tape support, but I cannot
remember the URL. See comp.os.linux.announce, it was posted a few
days ago. But parallel-port devices are usually rather slow.
