There are details here no one else would know. Why would there be only a single mention of Xenix, when Microsoft bet the farm on it, only to vapor it for 4+ (79 to 84) years and outsource it less than 3 years later. (87)

Vapor? Xenix existed, and worked well, on the TRS-80 Model 16. Many small businesses basically ran on a Model 16 with Xenix back in the day.
