Whoops. Sorry for the noise.  I should pay attention to *all* the
windows that were open when the  SpurVMMaker.image started.  I had
just read the overview which directed me to read the
StackInterpreterSimulator class comments.  To answer my own question,
now in the "VM Simulation Workspace" window I see...
   "Run the Stack VM simulator on a Spur image (by default the Spur
trunk 4.6 image,
    complex options are in the Cog example below)"
   [| cos |
   cos := StackInterpreterSimulator newWithOptions:
                            #(ObjectMemory Spur32BitMemoryManager).
   cos desiredNumStackPages: 8.
   cos openOn: 'trunk50.image'.
   cos openAsMorph; run].

which works fine.
