I see this as kind of an obvious hack...

If the emulator doesn't do direct writes to the screen in any
way...(you couldn't do this with the Pro350 emulator... I guess since
it emulates the graphics as well as PDP.)

Couldn't you get a getty up on Linux and then start the emulator under
it and then the console OPA0: device would be the TTY...

Not a second terminal, but it should let you run EDT and all of that...

The one problem is you couldn't really put a modem on it and
make it dial-up available since it's running logged in (usually as
root) and the user on that port could stop the emulation as well.
