An even better testing routine:

       xor a
       inr     a
       jpo odd
       xor a
odd:ret

I might have the opcodes wrong (I work both 8080 and Z80, no manual around).
Point is: inr a will set odd parity on and 8080--but is not an overflow on
the z80. This routine sets the zero flag if it is a z80, I think...
