Sure and I've even seen PDP8 emulation that clicked the teletype sounds
and and ran an Xterm window in 110 baud. (well, perhaps I was dreaming
on the sounds part).

If I smelled thoe overheated fans I'd have thought it was a real PDP8e.

As far as the windows part it isn't what I'm running (unless I have to
for work). My Vaxstation's starting to look like fun -- but I do miss
the PDP11/03 front end rx01 init clicks and the microdiagnostics.

But I can't afford the space or power for one in order to run the
microdiags to test wcs.

I did RT11 on the RT11 emulator on the Vax at DEC and the sysgens seemed
just the same as the ones on the 11/40 I used when I could borrow
it in the Princeton office and the emulated RT11 box could write files
to the floppy on the 11/780 that I could boot on my home PDT11/150.

Couldn't do that with the RK05's, RL02's and RM02's on the 11/40.
