Install the tek4010 emulator from this repo on a Raspberry Pi. I propose using
git clone git://github.com/rricharz/Tek4010
cd Tek4010
This allows you to get updates later easily as follows:
cd Tek4010
git pull
There is a file "captured_data" in the repo, which you can use to test the tek4010 emulator.
"captured_data" was produced in 2.11 BSD using my program "dodekagon". Type
./tek4010 /bin/cat captured_data -noexit
Don't forget the absolute path to "cat" and the LAST argument "-noexit", which tells
tek4010 to stay alive after cat has finished so that you have a chance to look at the output.
By the way, the "-noexit" as the LAST argument might also be helpful if you want to
experiment with other commands. Let me know if you find anything which works and makes sense.
Because tek4010 pipes from stdout of that program and into stdin of that program, some
programs will not work.
The emulator uses "rsh",
because historical Unix systems do not support the secure ssh, and because ssh does not
allow using a virtual emulator such as tek4010. You need therefore to install rsh
on the Raspberry Pi running the tek4010 emulator:

Expect a bit of slow down from time to time. In my test version the
PiDP11 software and the tek4010 software are using all 4 cores of the Raspberry Pi 3B+ running
at 70% CPU usage! It's amazing how powerful the Raspberry Pi 3B+ is!
at 60% CPU usage! It's amazing how powerful the Raspberry Pi 3B+ is!
You cannot use the tek4010 emulator running screens, as it is done in the standard setup
of the PiDP using the console, because screens filters the output stream of simh and is
therefore unsuitable for graphics terminals such as the tek4010 emulator. If you don't
want to change the standard setup, use <ctrl>e to stop simh, and then "exit" to quit simh.
