Long time ago I had 5.25" floppies for a Microport/286 Unix in hands,
later a 386 version of that. I think this was a real SYSV UNIX, not a
Xenix UNIX-lookalike. Must have been in the mid 80s, but eventually these
floppies got lost when the 386 and the various 386bsd and Linux
experiments came up. Unfortunately, this Unix died together with Microport
long ago, and not only I have lost the media set.
