Uh, you do realize that the Xenix rogue game (in the /usr/games directory)
is an 8086 (that's right, 8086) binary, do you not?

COSMOS and AKCS Xenix binaries, both of which alter character processing, run
correctly on 386/ix V2.0.1.  These are 80386 binaries; I have not yet tried
'286 code.  COSMOS contains calls to system routines that don't exist on
386/ix -- yet it works -- unchanged! (specific example -- "nap()")

In fact, one of these sites is running AKCS in production mode (ie: users on
without any knowledge of what they're doing), and it works fine.

AKCS's internal full-screen editor is about as "wierd on the terminal modes"
as you can get -- it's a full screen curses implementation, and goes into
and out of CBREAK and RAW modes many during the posting of a message (this
is what I am posting the response you are reading now from).

Again, these are all '386 programs.  I have also successfully run programs
that use shared libs from the 386/ix system (as well as Microport's 386
implementation) on Xenix 2.3, and they also worked without complaint or
problem.

I'll try a '286 and 8086 program and see what it does; perhaps there is a
problem there.  Then again, the ability to run these AT ALL is far beyond
anything 386/ix can pretend to do in COFF format....
