Someone has been using eZ80s & some Rabbit CPUs since their inception. The eZ80's don't run at 180MHz, they can run up to 50MHz but with some single cycle instructions.
The official development module & evaluation kits are at:
Zilog eZ80 Acclaim!
Alternatively there's the Rabbit Z80 derivatives:

Someone's also got a Texas Instruments TI-84 Plus CE Calculator. It's a eZ80 with a graphical output and USB interface.
TI-84 Plus CE
Some programmers have ported and written some great programs for it.

But if you do get one, make sure you don't get one with the most recent firmware that stops assembly language programs from being loaded apparently so students can't load cheat notes.
