Although it's not a system for production, a PDP-11 emulator that runs
under UNIX might be of interest to readers of this forum, perhaps as
an experimental testbed.  The emulator was written by "Der Mouse" at
McGill University, and can be obtained by Anonymous FTP from the host

    larry.mcrcim.mcgill.edu   [132.206.1.1]

Here follows the README text:

|  This is my PDP-11 emulator.  It should run on anything mostly-UNIXish;
|  I don't think I'm doing anything system-specific except possibly for
|  the tty and signal setup in cons_init(), which you can replace with
|  your preferred mechanism for getting the console SLU talking to
|  something useful.
|  
|  Please note: this is my development directory.  I make no promises that
|  what's here is in compilable shape even on the development system,
|  never mind your system.  If you have trouble, send me mail, and if I'm
|  not too busy I'll see if I can help.  And, of course, if it does
|  compile I don't promise anything about what it'll do, though it should
|  bear some resemblance to a PDP-11.  The Makefile will likely need work.
|  The simulator is currently atrociously slow (about a factor of 50
|  slower than the real thing on the development machine); I hope to add
|  some caching of the memory management stuff in the hope of speeding
|  this up.
|  
|  pdp11 is the emulator itself; as11 is an assembler that knows how to
|  generate output files of the sort pdp11 wants as input.  The .s11 files
|  here are some sample input files.  I tried to stick reasonably closely
|  to the DEC assembler syntax, though I must admit I was tempted to go
|  with the UNIX syntax instead...and I may yet add UNIX-style
|  single-digit numeric labels; they are a great convenience.
|  
|  aux.shar is a shar of some auxiliary routines that you will probably
|  find you need.
|  
|  There is basically no documentation on either as11 or pdp11 included.
|  I intend to write some, but haven't yet.
|  
|  Of course, by the time you read it this file may be out of date, since
|  I won't be updating it for every little tweak I make to the programs.
|  
|  Timestamp (should be updated at each change of this file):

I have not tried to use this emulator myself.
