There are several prep programs that take the tape files and make a .tap
file.
I ran into a YouTube video, that it is 5 years
old, titled "Ultrix-11
3.1 on an emulated PDP-11/73" and I found it very interesting.
It shows installation of Ultrix-11 under SIMH. The fellow steps through
the installation process and appears to be quite knowable.
I wanted to replicate it but couldn't locate the *.tap file used in the
video that was an image of the bootable TK50 distribution.
Bitsavers and tuhs.org have Ultrix-11 files, but not the bootable tape
image.
Anyone know where the tape image is located?
https://www.tuhs.org/Archive/Distributions/DEC/Ultrix-3.1/
has ultrix-3.1-bootape.tar.gz and seems to be, at first blush, the boot
tape (or its files) that you are looking for.

I took a look at that file and don't exactly know what to do with it. It
is not a bootable image of a tape, but rather the files that are on that
tape. Have to do some more digging. Its a learning experience.
