However, if the chart is correct there may have been Xenix versions for other 8086-based machines a year before that. Note that in this chart the “Xenix 2.0” and “Xenix 3.0” labels refer to MS internal versions, i.e. these numbers are not to be confused with the marketing labels IBM PC Xenix 2.0 and 3.0.

I am almost certain of the existence of a Unix variant for the Olivetti M24 which was an 8086-equipped PC (The M24 was rebranded as an AT&T 6300 if memory serves me correctly). It might have been Xenix or Venix but I honestly cannot remember it as I certainly recall Xenix floppies & manuals making the rounds later on 286s in Italy but I only faintly recall the M24 Unix.
