Deja Vu All Over Again - part the third

My daily travels through crossworld led me to consider the z machine, which led me to the wiki and this article on the current version of the z hardware. It's been a microprocessor chip for some years, which is kind of mind boggling for those of us who knew mainframes as glass rooms with raised floors. What appears not to have changed is 'COBOL Assist' after all these decades, although not, so far as I can tell, under that term

a new decimal arithmetic SIMD engine designed to boost COBOL and PL/I code

There's the just-birthed z15 chip, but not much info yet.
