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. bill
