I have a vague recollection that /dev/tty8 was the console in Edition 5 (we only used it briefly until Ed 6 appeared), but cannot find a reference =
to it; lots of stuff about Penguin/OS though...

Something to do with 0-7 being the mux, so "8" was left (remember= that
/dev/tty and /dev/console didn't exist back then), mayhaps?

Thanks.
