I would love to find out if this works (may have to try it myself).  Just
sounded like an interesting idea anyhow.  Normally I wouldn't have
mentioned it, but I thought about it for a second and figured there had to
be *some* reverse translation possible as the tk drive has to talk back
through the scsi drive chain to send info back to the computer.  Oh how I
would love to hang my dat drive off my uVaxIII.
