So you are saying I can't IPL OS/360 on our z13 :) -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Peter Relson Sent: Monday, November 27, 2017 8:58 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: OS/390 2.5
[External Email] I don't know the official answer, but a way to guesstimate a quasi-sane answer: Pick whatever machine was made available 3 years after OS/390 2.5 became available. Any machine available after that would most likely not have had any exploitation support provided as far back as a release 3 years old, but might have had toleration support. Add another 3 years and come up with that machine and you'll likely not have had toleration support either as far back as OS/390 2.5. That would then be the machine that you should not be at all surprised if OS/390 2.5 did not run on. Although I suppose it is possible (I do not recall) that back then we provided support "further back" when a new machine came along.
