Yes. We actually have that at Update, in form of a real PDP-11/70 with 
this code installed. However, the machine is down much of the time at 
the moment because of the cooling system needing to be fixed. (It's been 
this way for years, but we are making slow progress on it.)

Well, you already have most of the sources, as everything except the 
device drivers comes with sources.
But I'm going to make the last bits available as well, but it's not 
going to be super easy for someone to work on, or modify those parts. It 
will be more like a snapshot of my build system.

And building the whole distribution takes about 1.5h on a real 11/93 
with modern disks.

But for people who actually wants to read several hundred K of 
MACRO-11... Here is your chance... :-)
