Well, obviously there are differences. The TE16 is a Massbus tape drive.
The TS11 is a Unibus thing. Totally different. Both in how they connect,
how the programming model is, the exact layout of registers, and of
course then, through which bus interface you program them.
In essence, they have nothing in common, apart from that they both use
the same physical tape medium in real life.

Thanks to Wilm, I now have VMS 1.5 up and running. This is new territory
for me since my first exposure to VAXen was in late 1982 when the
version was something like 3.0, or just possibly the last version of
2.x. (I didn't pay attention to such things back then. If I could write
Fortran programs, I was happy.)
However, the fact that I could complete the installation of VMS 3.0 by
using a simulated TS11 tape drive when it failed with a TE16 drive has
got me wondering if there is a bug in simh. Surely on a real system you
could use a real TS11 or TE16 drive? Obviously there is no density on a
simulated tape file, but is there any other difference between the two
simulated tape drives that explains what is going on?

Thanks Wilm, I will try that out. I doubt I would have thought of
using a TS11 rather than a TE16 without your advice.

Your approach is correct, I have regularly used it over the past
weeks to bring up VMS 1.0.
I also saw these CRC errors on restore sometimes. There are two
ways around this:
1. Mount the 3.0 tape on a generic (newer) VAX/VMS system, use
$MOUNT/OVER=ID and copy the LIBRARY and OPTIONAL savesets to a
(RP06-sized) disk in the [0,0] directory. In a later step, $
mount
/foreign this disk, and point the installer to this disk as
the source.
2. On your 3.0 system just booted with just the REQUIRED
saveset, use a
TS11 and not a TE16 tape unit in the simh config. Somehow this
worked. Also, when you use a TE16, use an explicit $MOU/FOR
/DEN=800. I forget in which version, but this also worked
sometimes.

Encouraged by all of the posting about running VMS 1.5 on an
emulated VAX 780 with simh, I have tried to do the same.
However, I am having a problem.
I don't have an existing VMS 3.x system running (4.6 is my
earliest), so I tried to do a VMS 3.0 installation using the
tape from uni-stuttgart which I had downloaded some time ago.
I booted a VMS 4.6 system on an emulated 780 and did an
image restore using BACKUP of the REQUIRED saveset on the
VMS 3.0 installation tape to an RP06. So far, so good. Then
I booted the newly created RP06 disk, which continued the
installation process by attempting to restore the LIBRARY
saveset on the VMS 3.0 tape. However, this crashed with too
many CRC errors.
This is where I am stuck. I could download the tape from
uni-stuttgart again, but is there any reason to expect a
better result by doing this? Can someone who has got this to
work advise me what to try next please. I have downloaded
the files that Christian posted, but while that has
standalone backup on a disk image, I need DSC to read the
VMS 1.5 tape (don't I?) which is the only reason that I was
trying to get VMS 3.0 working in the first place.

You may also want to try VAX/VMS 1.0 (or as close
as you can
get to it):

This is not taken from an original tape. It's
something I
reconstructed
from a disk containing early VAX/VMS source and
binaries. The
dates
indicate that this is earlier than VAX/VMS 1.5.
Hopefully someone can find an original at some point.

Wonderful!
I now have VMS 1.0 up and running on simh VAX780. Does
anyone know
whereto find the Fortran installation tape for this system?
BTW, I also use a fine VT52 emulator I found on github.
