I was there at time when AT&T was negotiating the replacement for the V7 license with 10 of us (the 10 firms included Microsoft - the only time I can say I was in the room with Willy G. - but that's another story)​. This work would become the System III license. > > ​Xenix, which was V7 based originally, was target for the generic 8086 systems (as well as PDP-11, 68K and Z8000) but the Intel support was generic so it included the PC. [...] Yes, you are correct: In november 1981 Xenix ran on the Altos 8600. Once you run on one 8086 machine, the next is minor step. https://en.wikipedia.org/wiki/Altos_Computer_Systems#ACS_8600 Your insights about licensing match with the chart on the ‘seefigure1’ website, and help explain some things about it.
