We have two DEC TU-81 tape drives, all up to current ECO levels.
One of them is on a 785 running Ultrix 1.2 -- the other is on
a 750 running 4.3BSD (stock drive handler software).  Both seem
to be flaky ever since we started using them (we used to have a
TU-77 and a TU-80, respectively).  The 785 hangs/crashes often
while using the tape drive.  The 750 sometimes hangs the device
and zombies the process; we have to reboot to get the drive back.

Has anyone else had problems with this drive?  We have a TU-81 plus
on an 8500 (running VMS) and had some problems with the controller
but things seem to be stable on it now.  It's the TU-81's on the
U*ix machines that are causing grief.

Thanks for any insights.

..Bob

PS We tried the TU-81's on the 8500, they act pretty reliably.
