If you can get a SCSI card for a PC, or a unix system with SCSI disk interface,
you are golden.
Here is what I did to get 2.11BSD over to my 11/44 with an Emulex UC18 SCSI
controller:
(1) Use SIMH to configure/build a working 2.11BSD system from scratch tapes, if
you desire.
(2) Or you can get pre-built 2.11BSD image from here:
http://www.ak6dn.dyndns.org/PDP-11/2.11BSD/
or other locations on the net as well. The image I built is current thru
the latest patches.
(3) Mount the SCSI disk on which you will be installing the 2.11BSD image on
your PC/linux box. Use 'dd' to blast the whole image (from (2)) to the disk.
(4) Dismount the SCSI disk from your PC/unix box, carry it over to your PDP-11,
install it, and boot it up.
Any way you can do a byte-for-byte copy of the SIMH .dsk file to your target
SCSI drive should probably work.

Is the UC07 supported by 2.11BSD? I know that when I
considered installing it
on my PDP-11/73 that it had issues with my Viking QDT SCSI Adapter.
As far as tape issues, I use a DEC TLZ06 4mm DAT on my PDP-11/73, as well as a
TK50. I was able to install RSTS/E from 4mm without any problem, but couldn't
install layered products from 4mm, for those I had to use TK50's. I don't
know if there could be any strange issues like that or not. A DLT8000 drive
is quite a bit different from a TK50.
I'll check with a couple people I know, and see if they have any idea. I am
wondering if you can even boot from a DLT8000 drive.
BTW, is the drive HVD, or something else? I believe that all of the DLT8000
drives we had were HVD.

Hi,
I've been making progress with my pdp11/53 project. Once I figured out
how to get into Emulex F.R.D. mode from ODT, I was able to configure,
format, and test my QD01 connected MFM hard drive.
I'd like to try installing 2.11BSD. Although I've got a TK50 drive
and controller, I don't have any tapes, or anything else here that
can write to them.
I have a Quantum DLT8000 SCSI drive, and an Emulex UC07 scsi controller.
I was able to set the UC07 as the first TMSCP controller, and F.R.D on
the UC07 reports the DLT8000 drive, and tests writing and reading to
tapes loaded in the drive with no errors.
I followed the 2.11BSD setup.ps and HOWTO file instructions to create
a tape with dd, using a Sun Solaris SPARC server connected to the DLT8000.
It seems silly trying to install an OS on a 70MB MFM drive from an
80GB DLT tape, but that's what I've got to work with so far, and my
UC07 can't do TMSCP and MSCP at once, so no SCSI disks if I'm installing
from SCSI tape.
Back on the 11/53, if I try to "BOOT MU0", the DLT tape spins for a few
seconds encouragingly, but then I get:
KDJ11-D/S E.03
Media not bootable
Should I be able to boot the 2.11BSD boot block on an 11/53 from a
TMSCP connected SCSI tape drive? The BSD setup.ps file includes bootstrap
monitor examples for TM and TS tape drives. Do I need to use one of
these instead of the normal 11/53 bootstrap ROM? Or, maybe there is
something about block sizes and writing the tapes from Sun Solaris SPARC
dd that means they aren't compatible?
Alternate paths I could take might be installing 2.11BSD using VTserver,
or maybe using PUTR or an emulator to set up OS directly onto a SCSI hard
drive or zip drive for use on the 11/53, but I liked the idea of doing it
with tape if I can figure out how. I have successfully booted the 11/53
from an RT11 RX33 floppy I created with PUTR, for what it's worth.
