Why do you say that? 

The ZAX ICE that I have seems to consist basically of a Z80 processor, 
memory to capture actesses to the target system (a sort-of dedicated 
logic analyser) and not too much else. The Z80is switched beterrn the 
target system, and a monitor program in ROM in the ICE box which lets you 
examine/chnge memory, registers, etc.

OK, it's 3 or 4 boards of chips, but that's by no means the most 
complicated thing I've worked on.
