Yup.  Apple had a Z80 card.  The Commodore 128 had an expansion cartridge with
a Z80 and the ability to run CP/M.

The company that Microsoft purchased what would become MS-DOS 1.0 from had a
business of doing those kinds of add ons.

The original IBM-PC, though, was a little different.  Unlike the 6502-based
computers, it wasn't going to use a Z80 add on card.  They were porting CP/M to
the 8086/8066 family.  It wouldn't run the Z80 software, but it would be really
easy for software companies to port their software over.

 pF> IBM won that battle, you don't see any Apple IIIs around anymore.  :)

The Apple III was a strange bird anyway.  I think is disappeared for other
reasons.

But actually Microsoft won the battle.
