I am using this one (OK, it is a Quantum DLT4700):

sa0 at ahc0 bus 0 target 4 lun 0
sa0: <Quantum DLT4700 D991> Removable Sequential Access SCSI-2 device
sa0: 10.000MB/s transfers (10.000MHz, offset 15)
ch0 at ahc0 bus 0 target 4 lun 1
ch0: <Quantum TZ Media Changer D991> Removable Changer SCSI-2 device
ch0: 10.000MB/s transfers (10.000MHz, offset 15)
ch0: 7 slots, 1 drive, 1 picker, 0 portals      


The firmware for the DLT4xxx can be found at:

ftp://ftp.quantum.com/Tape_Firmware/DLT4000/

Don't know if it is DEC compatible...
