not really obscure. there where several s100 system that started out as
z80, then updated as z80/m68k.
most would boot up z80 and then transfer to m68k.
1] there where also z80/m68k cpu that could pass off to z80 any task
that work i/o.
2] within these, z80/m68k, i/o cards had their own z80 w/memory and
z80 family i/o chips.
3] when making i/o transfers, z80 could grab main memory and pull in
data while m68k was working internal operations and using on board
using these structures made for some fast data handling. plus, considering
their clock speed, they could hold their own in today's standards.

?uzi? | ?uzix? sounds strangle familiar, but recall does not bring it up.
what i am familiar with is the machine pistol made in israel and a very
fine peace to fire.
i never had one, no 'class a', but i have some friends who own them.
in a free world without fences, who needs gates.
help microsoft stamp out piracy - give linux to a friend today.
to mess up a linux box, you need to work at it.
to mess up an ms windows box, you just need to *look* at it.
