Your not serious?  Z80 or 8080 to 8086 is not too bad but the other way
is plain nuts.

Its not nice code either.  It assumes a memory mapped video, as in the
PC video.   Kaypro is a pretty close example of that but this will not
be used
on a kaypro.

The executable did run ok in .dosemu.

Pretty nasty as Z80 does not know of segments, DOS IO, or can be assumed
to have a memory mapped video.  For S100 that would be a PT VDM-1,or one
of the similar flavors.   If it were my usual S100/Kaypro/AMproLB+ or
any of
the CP/M machines I have its VEDIT.

But this machine is maybe 1/3rd the size of a S100 card. All IO is
serial initially.
