I should have also mentioned:  the sticky EOF occurs on the MVII TK50's,
but *not* on the 6250-BPI reel-to-reel drives on the very same machines.

So it's not even a workstation/microvax difference, but a difference
between units on the same machine!  Nice portability, eh?

do you happen to have your backup on a regular tape?"
