If my merory serves me correctly, the Z80 also has a *pair* of register
sets that the user can toggle between, whereas the 8080 only has one set
of registers.  Also, the Z80 has a few auto-incrementing opcodes which
help in block-mode data transfers.  Perhaps the previous poster was
referring to the difference between the 8080 and the 8085 (which *are*
almost identical for 5v-only power supply and 2 (RIM? or similar) opcodes).

I'm confident that the job could be done without a real lot of effort,
but Z80 code is not downward compatible with 8080 code.

Hope this helps.
