How original do you want to get? :)
There's a Unix V5 (*not System V*) running in Javascript here:

To run, type:

You can run ed on /etc/passwd.
"pp" works and prints the line twice.
"ppp" doesn't work but neither does "pl", "pn".
"n" prints an empty line. "l" doesn't print a dollar sign at the end
of the line.
