Last time I checked, a z-series IO processor was a normal processor that just want licenced to run application code. Same as how their COBOL processors are the same as their Java processors, despite being more expensive.
AFAIK microcode is the big part of zCPU, that allows reconfigure the way how zCPU works internally, despite the fact on precise hardware level it's still the same zCPU.
