Maybe not. IIRC, the TU78 had a bunch of teething
problems. I definitely remember many 2 AM phone calls
from the night shift operators when the overnight backup
runs failed (I think the tape would run off the end of the
reel). Much back and forth with the DEC hardware and VMS
engineers before it finally got fixed.
We had a very early TU77, and went through a bunch of issues
with it, TOO! mostly due to tape overheating and sticking
to the heads. You could hear it from the next room, a
pop-pop-pop every time the tape started moving. Cleaning
the heads every 3-4 tapes during backup.
