That means an 8086 can run 8080       instructions - but the reverse is not true.              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?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
