Not exactly.  Zilog did indeed have a z8000 (not 80,000).  The stillborn
z800 became the z280, not the z180.  The hd64180 was an independent
development by Hitachi.  When Zilog and Hitachi made a deal for 
Hitachi to make the z280 (z800) Hitachi agreed to let Zilog make the
64180 and call it a z180.
