At least > I never had to work with a tape in more than one density... A "feature" of the DEC TM02 tape formatter (some still in use today) is that it will gleefully change density when told to (between 800 and 1600, or course 8-). Now, the fine folks at ANSI have decreed that this is a definite no-no and all that, so (rather than fix the hardware) the various and sundry DEC operating systems that support this formatter now check to see if the BOT bit is set before accepting a set density command.
