  I have Alan Snyder's C compiler running 
Way cool! Congrats!
Where did you find it? Do you have source too?
  there may also be machine descriptions for Honeywell
6000 series and
 PDP-11 
There _was_ one for the H6000, not sure about the -11.
  At some point it seems like this compiler was tangled
with Stephen
 Johnson's PCC. 
It would be good to find out what, if any, the connection is.
