I don't suppose so.  You can run the target code through a disassembler
and see what you get.  If you are sure you are in code and see JR to
a reasonable address, it's Z80 code.  If you see only JP (JMP) instructions
is is probably 8080 code.  8085 is identical to 8080 code except for
the SIM/RIM instructions (8085).  Most CP/M applications are written
in 8080 code so as to function equally well on 8080/8085/Z80 cpu's.
