It should work, provided you aren't trying to write tapes with blocksize
> 4 KB.  I back-ported the pcscp driver to NetBSD 1.3.2, using the code
from -current around 26/1/99.  The patch which Izumi Tsutsui (who wrote
the pcscp driver) submitted a few days ago (kern/7252) has fixed the
problem writing large tape blocks.  But even without that patch, the
driver appears to work for everything else apart from tape writes > 4 KB.
For example, I was able to duplicate my EIDE system disk to a borrowed
SCSI drive connected to my Tekram DC-390 and boot and run from it for
several hours with no problems whatsoever.
