I had thought s390x could be based on POWER8/9, but you're right, that doesn't appear to be the case. I apologise. Regardless, Go does consider S390x to be a separate port.
- jacques_chester 10y agoAs I understand it, the s390x ISA is fully backwards compatible to stone tablets. But it's essentially a POWER chip with a bit of extra decoder logic.
- wmf 10y agoThere's actually very little in common between z/Arch and Power, but I don't blame you since "everybody knows" they are the same thing.
- StillBored 10y agoYah, most of the descriptions (just a little extra decode, aka PowerPC AS), and sharing the hardware actually apply to the iSeries, which _IS_ POWER based. But of course that is a minicomputer not a maninframe... It seems the vast majority of people who consider themselves knowledgeable about computers are just massively ignorant/confused by IBM's product lines and capabilities (and don't even get me started about the nonstop and openvms). Which is a bit of a shame, particularly in the case of IBM i, which is probably one of the most interesting OS's still in support/production.
