Fascinating.  Do you also do your own vaccine research with similar 
methodology and results?

  You might consider these sources:

  I have 43 years of experience at IBM in MVS-OS/390-z/OS development and have 
worked with the processor engineers over most of that interval.
Knowledge that  you have from Andor Systems designing a 3090 compatible system 
over 30 years ago would be somewhat outdated.
The IBM 3090 bipolar machines of that era did have an underlying hardware 
architecture upon which the 370/ESA architecture was
implemented in horizontal and vertical microcode.  However, things are 
considerably different in more recent generations
of processor design.

After doing more research, I will stand by my retort.  

The BASIC CPU hardware for zServer is a collection of POWER PC processors with 
some addition z Enhancements and the z is an EMULATOR because the last 
HARDWIRED CPU was probably the S/360 & S/370 model 195. 

Even Intel CPUs are Emulators .... that is that are a RISC engine ( like the 
POWER PC )  running the INTEL/AMD X64 instruction set with lots of microcode ...
