Interesting point. IIRC, the Macintosh PDP-8/e emulator has an option to run
at native speeds, however, I don't think any of the PDP-11 emulators do. Of
course other than clock skew that I've seen, the faster the PDP-11 the better
:^) Same thing goes for the PDP-10, the faster the better (and on at least
the simh PDP-10 emulator the clock skew problem has been solved).
