CPM86, 8086/8 would use it as a slave (8089) assuming the bios was written
for it. Though I do have a z80/8089 paper exercise that would work.

the 8089 never had it's own OS or anything like that. Iwas basically a
channel processor for IO.

That teamed with a Isbc86 and lots of ram made a hot system.
