Yes, they can.  I've been doing it for years.

I've not tried SHRDLU on ITS.

I remember seeing this under ks-kn10, but don't remember what the fix was off
hand.  I'm away from my computer until later this week, so I'll have to look
that up and get back to you, probably not on the SimH list.

The SimH KS-10 is much better behaved for ITS, in my experience; I only use
KLH10 for Tops-20 v7.x and Tops-10 v7.04.  Then again, I usually use the real
hardware at the museum for all three.

You need to look at Bjorn Victor's intro pages http://victor.se/bjorn/its/ for
how to set things up, even if you think you intend to use Ken Harrenstien's
distribution on the PI disk image (which you will have to convert to SimH
format with the KLH10 tools).
