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.
There are several prep programs that take the tape files and make a .tap
file.

I unzipped all the cctalk images I have and in the 2000 time frame
there's a discussion about running 3.x version and upgrading to 4.x.
Fun to see digression into how Netscape is having trouble with java
extensions to the Altavista search engine they were looking for
image info with.
This is the closest to the subject I found. No references to any tape
images of the 3.x version.

that far)

I have an image of an Ultrix V3.1 upgrade tape I can send if you want to try
it. You should be able to mount it as a tape in the simh vax emulator and
boot it. If you want to go a little further, I also have V4.x images.

Thanks
