Your not serious?? Z80 or 8080 to 8086 is not

is plain nuts.
The whole thing comes from a project for
myself...?
I wanted a very basic screen based editor written in 8080/8085/z80 asm
and compact
(as in under 4K).? I figured first lets inquire of the Internet to see
if I need to and code exists...
I remember typing in TED.ASM from one of the PC
magazines in the late 80s.
Yes, it's for MS-DOS, but:
1) The 8086 is somewhat, kind of, source compatible with the
8080/Z80 (if you squint hard enough) 2) It was 3K when assembled into TED.COM
Its
not nice code either.? It assumes a memory mapped video, as in the
usual
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.
3) Was full screen. And quite basic.
I'm not sure how hard it would be to translate it to 8080/Z80.
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.
