I had heard that Microsoft had licensed Xenix before the IBM thing. Bill
thought he had a gentleman's agreement with Gary to not intrude in each
other's turf and then DR came out with CBASIC. Furious, Bill got into
operating systems in retaliation.

When IBM came to Microsoft for an OS they had specs for a machine that
was in no way up to running Xenix. So it is just simpler to tell the
story as "Microsoft didn't have an operating system". Adding DOS
complicated things for Microsoft so they planned to evolve the two
systems towards each other until there was a single one. The January
1982 Byte says instead that there would be 3 systems: Xenix at the high
end, DOS at the low end and a hybrid in the middle. MS-DOS 2 was
essentially this hybrid (so most system calls have two versions: a CP/M
one and a Unix one).

Hmmm... here it says that though CBASIC was developed in 1976 it only
became a DR product in 1981, which is too late for the story I told
above to make sense:

I have just watched a talk with Gary where he introduced DR Logo. It
wasn't much cheaper than that. And at the end somebody asked about the
soon to be introduced C compiler and the answer was that it would cost
$600.

They installed barbed wire in the air ducts going into the room with the
prototype.
