This really doesn't seem to have much to do with Xenix.  Yes, he
mentions it briefly, talking about licensing, but that seems to be
all.

FWIW, Xenix preceded DOS as a Microsoft operating system.  From my
personal timeline:

6 September 1980: At Euromicro 80, a conference in London, I heard a
  	    	  presentation about Xenix from a Microsoft person
  	    	  whose name I no longer recall.  It was supposed to
  	    	  have been from Bill Gates, but he had a last-minute
  	    	  cancellation.

December 1980:    I bought a pair of S-100 boards and an operating
	 	  system called 86-DOS from an obscure company in
	 	  Washington state, USA.  I spoke on the phone to a
	 	  Tim Paterson, who assured me that 86-DOS had a
	 	  bright future.  The rest is, of course, history.

June 1981: 	  Byte magazine carried an article from Microsoft
     		  about Xenix.  This was presumably written no later
     		  than May 1981.

August 1981:	  IBM released the PC.

I've done a bit of searching and found this link:
https://computeradsfromthepast.substack.com/p/microsofts-xenix which
tells me that Microsoft (really their SCO) licensed 7th Edition Unix
in 1978 and brought out a product 2 years later.  That seems
plausible.

Does anybody have a programme for Euromicro 80?
