It would be helpful to those who might be able to help you to know what make
and model your Z80 machine is.  As you probably are aware, each manufacturer
elected to use his own combination of port addresses and peripheral chips, and
CP/M is not very portable from one make (sometimes, one model) of machine to
another.

Do I also infer that you are running DOS 2.11 on the same machine?  There are
only a few that have that dual capability.
