The Z80 is a superset of the 8080 at the binary code level (that is
a binary 8080 program should run on a Z80, but not the converse, since
the Z80 has at least the IX index register that the 8080 doesn't have,
and hence the Z80 has additional instructions that the 8080 doesn't have).
The source code mneumonics for the older 8080 instructions were not
preserved however.  However, it is pretty easy to "hand-compile" 8080
source code into Z80 source code, once you get the hang of things (I
remember doing this several years ago).  Digression: The Small-C compiler
written by Ron Cain (published in Dr. Dobbs Journal several years ago) was
originally written to output 8080 source code.  It was relatively easy
to change it to output Z80 source code instead.

Therefore, if you plan to convert Z80 source code to 8080 source code,
you will have problems for those Z80 instructions which have no 8080
counterpart.
