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? More of my recollections at http://www.lemis.com/grog/diary-sep1980.php#21 Greg -- Sent from my desktop computer.
