I've run it using simh, but not actually _used_ it at all.

Aye, there's the rub...

It's supplied in bin tape format with Bernhard Baehr's PDP-8e emulator for 
the Mac and I've run it, under os/8, to the point of loading and running the
supplied Towers of Hanoi program but I don't know enough about focal to 
comment further.
Focal needs some patching to run on the emulator as it apparently expects
interrupt driven i/o, but Mr Baehr supplies a patch.
