Hi
??? I am working on getting my KDJ11-E based system up.
I have a CQD220A and a SCSI hard drive installed and formatted.
A serial connection to a Raspberry Pi soon brought up the console on the
PDP-11 using TU58FS.
Next will be a second serial line to allow TU58 emulation. SFSG
What is not clear is if I can get a bootable OS (RT, RSX or whatever)?
image onto the Hard Drive using TU58FS.
Any advice as to if and how this could be done would be greatly
appreciated .

Yes you can. Basically you can boot an image and then prepare the volume on the hard
drive and copy it over. I have a PDP11 page on my Classiccmp site that walks through it.
There?s also a long thread on the VCFE forums about it.

Is getting set up to use TU58 emulation and then using that as a
software installation source one of the goals on its own, or is that
just one of the solutions you are considering in the larger goal of
getting software up and running on your 11/93?
If you are open to other software installation options, it should be a
lot quicker and easier to install software to a disk image using SIMH,
and then "dd" that image to a SCSI disk that the CQD220A is configured
to use. I have gone that route a few times to get 2.11BSD and RSTS/E
10.1 running on real PDP-11 hardware with CQD-220 controllers.

Hi
??? It does not have to be done using TU58.
If you would be so kind as to explain the bit about SIMH and dd.
What to do is good.. How even better.
If I can get? a bootable OS image onto the SCSI drive with what I have
available then that's all I? need.

The idea would be to use another machine (say, a PC running Linux) to
copy an image that runs under SimH configured for the same disk
controller and geometry to copy that image to the disk.

Or use Ersatz-11, mount the disk and build the image right there.
I have done this for RT-11, RSTS/E and BSD-2.11.
