Now that I think about it, I don't think there was ever an i390 -- although there was an i370, which died a long time ago (based on the very first port of what was then not yet z/Architecture, s390 took its place when IBM decided it'd participate in GNU tools development way back circa 2000/2001. s390x (z/Architecture) was introduced almost immediately after s390 came on board, and it seems to be the ID "with legs". In modern terms, i390 means nothing (unless someone would care to revive it), s390 means XA, s390x still means z/Architecture as it always has.
You're right. The s390x tag isn't used much outside of GNU/Linux & BSD circles. Too bad. I think it's a very convenient shorthand (not to mention 10 characters' less typing to do), YMMV :-) Jim Tison z/TPF Systems Programmer IBM Services From: Rob van der Heij <[email protected]> To: [email protected] Date: 10/13/2019 11:50 Subject: [EXTERNAL] Re: Why Linux Developers Should Reconsider IBM Mainframes - Linux.com Sent by: Linux on 390 Port <[email protected]> But it’s true that those terms are not used outside Linux on System Z. Even though zArchitecture isn’t an appealing name. And we don’t hear much about i390 anymore 😋 On Sun, 13 Oct 2019 at 15:41, Neale Ferguson <[email protected]> wrote: > Yes and still is.
