It took a day because I wanted to test it but I have a TK50 image that

two RD54's. Worked fine. It's been a while since I did any Ultrix-11
on real or simulated hardware.
Have no idea how to get this tape to anyone. It's just shy of 4M. Not
sure if it could be emailed. The SIMH ini file is trivially simple but
I could provide that as well.
I have nowhere I could put it up for download. I don't do things like
Google Drive. Maybe we need a GITHUB site or something for Ultrix stuff.

Would presumably be a lot smaller gzip?d?

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.
