I just obtained a 50 pin SCSI drive for my 11/83, so now I'm ready to go!
I had asked once before about installing BSD from a SCSI tape on my
controller and was told that it should work. I've got one problem, though
-- I'm not sure how to write the tape. I've got the distribution media --
I just don't know how to write it so that BSD will read it. I thought
about just formatting a second disk and putting the distribution on that,
but I haven't got a real system (yet!) to create it from...
Any suggestions?

Here is a THEORY, that I haven't had time to test. Put the disk on a system
that runs SIMH or E11, 'dd' it to a disk file. Use that disk file as the HD
image that you install the OS on using either SIMH or E11. Then 'dd' the
disk file back to the HD, install the HD in your PDP-11/83, and boot.
Please note this is a THEORY that a couple of us have discussed for other
PDP-11 OS's that no one to my knowledge has had the time to try, but there
is a good chance it will work (though Unix might be a bit more picky).

It does work. I used that method with simh to create a set of 9-track
installation tapes for 2.11BSD on a pdp-11/73. At the time, I don't
think MSCP was supported by simh so I used maybe an RP07 in simh to hold
the system. I 'dd'ed the image directly to the SCSI disk after making
sure there was a kernel that could handle MSCP. I booted the standalone
system from an RX50 on the real hardware and then started unix from the
SCSI drive. I then wrote the tapes and restarted the installation from
new tapes.
Now that simh supports MSCP, TMSCP, and ethernet, it would probably be
faster to generate the system on simh completely, including 'localizing'
for networking and your hardware, than to do it on the real machine...
But then that wouldn't be nearly as much fun...

Mount the tape drive in an other *ix machine and use
maketape from the
2.11BSD distribution to write the tape. (I swaped the PDP-11 CPU + RAM
for a MicroVAX CPU + RAM, netbooted NetBSD and wrote a TK50 tape. Swaped
everything back and instaled 2.11BSD.)
