I would be interested in a copy of the SCSI spec as well.  I haven't been
able to find anything useful, however I haven't been looking all that hard
either.

I'm not concerned about the ``st0: bad request, must be between 0 and 0''
error as I am the ILLEGAL REQUEST.  This didn't start to show up until I
installed 2.0.5-Alpha.  I haven't had a chance to try a different tape drive
to see if there is a problem with the drive, but I find that unlikely.??!  I
did a make world with the sources as of June 23 and I am still seeing the
problem.
