>=20
>     Z80/Z8000 - CPU used by the Texas Instruments line of calculators, but
> also previously used in early microcomputers. This line is heavily based
> off of the original Intel 8080, and was created by Intel engineers after
> they split off of the parent company and formed Zilog. A derivative
> Z80-GB is used in the GameBoy and GameBoy Color -- there may be other
> places it is used. The Z80 had a unique capability of swapping the
> current working set of register values with another hidden set of
> registers called "shadow registers".
>=20
>     RS/6000 - RISC CPUs used for scalable computing    in IBMs RS/6000
> parallel computing cabinets.
