Hm,  I just happen to have a IIgs system I'm not doing anything with...

Back in the day when I worked on a lot of this stuff,  I saw a fair number of 
both CP/M boxes and c= stuff,  and one time did actually take a few minutes 
and boot CP/M on a 128/1571 combo.  It ran,  and I was able to take some of 
the software that I was used to running on other platforms and run it there, 
but I was not all that impressed with the way it ran-- it was slow.

People should also be aware of the misleading stuff in the way the speed of 
that part is presented.  They called it "a 4 MHz Z80" but even though it was 
indeed that chip the way they had it configured in there was so tightly 
coupled with the rest of the system that it only ran some of the time,  
rather than all of the time,  giving an effective clock rate of somewhere 
around 2.5 MHz.
