Yeah, but the fastest that is really available are Z-80H, running at
8MHz.  Faster ones are called 180 and 280, and they are a bit too complicated
to be speeded up that much or to remain our dear friend...

P.S.  Z80H used to be 10 MHz in the development stage.  I don't know what
happened, but everyone, including Zilog, AMD, Hitachi..., decided that
it will just run fine at 8.  Oh, well.
