I believe the Z-80 was subordinate to the M68K.   The Model 16 was developed
independently of the Model II.  While Tandy had a version of Xenix to 
sell for it
it shipped with TRSDOS-16.  It also ran CP/M-68K rather nicely.  It was 
a good
machine destined to die when Tandy decided not to be a computer company.
