 So many Z-80 CP/M machines... were they compatible, to a reasonable

 called MSX. More info on that?) 
Z-80 CP/M machines were compatible in application software
forever.  Disk format varied.  If they used S-100 boards, they
had compatibility there.  Usually.  MSX died like a pig and
deserved to.

                        before they're allowed to be free?

                        they'll never be free.
