   Rockwell PPS-4 documents needed. MM7X st

   Hi Folks,   
      
   I've done the online searches, and know that bitsavers.org (Hi Al K. if   
   you are here) has a reasonable amount of information, however I am   
   looking for ap notes and more information than is currently archived.   
      
   At the moment one chip I am researching is the MM76E (not the 40-pin EL   
   version) ROM as I can't find the pinout anywhere - so far. I can figure   
   it out, but it is always better to have the manual if possible...   
      
   Any documents found will be off to bitsavers of course, but I'm hoping   
   that someone here has an ancient (70s!) Rockwell manual on these 42-pin   
   spider chips!   
      
   Did anyone ever make an emulator for the MM78 CPU family?   
      
   Thanks,
