    You didn't say how your Exabyte is connected to your VMS system(s).

    We are using a CMD CQD-263/TM for our EXabyte 8500 (I forget the rev#) on
    our VAX 4000-300 which allows toggling between 8200- and 8500-mode with
    the INITI/DENSI= switch.  /DENSI=1600 ==> 8200-mode, /DENSI=8500 ==>
    8500-mode.   If you also have a third-party controller, you might want
    to check with them to see if they have an option for you.
        (btw, the Exabyte on the CMD controller emulates a TU81.)
