I can confirm it. It is more or less like IFP. However IFP is just

zAAP was pitched as (and used for) offloading Java from the primary
engines. Neat idea!
It was several weeks, perhaps a few months, before I realized that the
zAAP was *not* a Java processor. Since it's all about microcode, I

And I also like that IBM's CPU's can be configured in so many different
