   There was a translation program required to   
   convert 8080 source into 8086 source.   
      
   But even if that was not required, that   
   still doesn't answer my question.   
      
   I'm after an 8080 replacement that does a   
   SUBSET of 8086 tiny model instructions.   
      
   Is that possible, or is there a technical   
   issue in switching between 8 bit   
   and 16 bit such that the closest you   
   can get is source translation?
