I've got one and it seems to work. It presents two interfaces to the
computer for changing tapes. First, LUN 1 is a standard SCSI changer
device, and will accept change commands. I think there's a driver
somewhere.
Second, if you eject a tape, then it'll automatically load the next
tape. So *anything*, even without SCSI changer support, will work.
JEM Computers (www.jemcomputers.com) has them for about $360 each,
refurbished. That's not bad for a DDS-2 drive :-).
