Lots of DVD drives use embedded Z80's as controllers, including the dual-layer 
drive in my laptop.  Never thought that my teenage years spent hacking Z80 
machine code on a TRS-80 could produce a currently marketable skill.... 

Quick, Z80 joke coming.... Addr: 0000:21 00 00 01 FF FF 11 01 00 ED 
B0.......Will it finish?  

Same is true of MIPS and PowerPC, though.  There are far more MIPS chips in 
routers than ever saw desktop use in SGI workstations; and while it might take 
a little while for Cisco's PowerPC driven routers' CPU's to outnumber all the 
PowerMacs our there, one day it will happen.

And then all those PowerMac assembly language gurus might prove useful in the 
router side of the house.....
