These points really aren't enough to know whether OS/390 2.5 will IPL and

This all comes down to what the site is willing to do for their long term
viability. If they are happy with the current release and hardware, and are
willing to live with the fact that at some point in time they just won't be
able to fix the hardware, then they obviously are welcome to pay IBM

The IBM z800 (and z900 for that matter) never officially supported OS/390

Why would you even waste your time with these idiots, Mark ? They have
screwed themselves into the ground.
You can bet your boots the same team of management clowns who brought this

Any machine available after that would most likely not have had any
exploitation support provided as far back as a release 3
z/OS. I ended up writing a
program to to the full pack backups and restores. DASD to DASD would have been
much better, but they had REAL 3350's and 3380's and only FICON RAID on the new
system. That was a real test of the process.:)

Hi Folks,
I have a client who is running OS/390 2.5 and they cannot upgrade their OS for
many reasons, let’s just not go there!
They have asked what is the latest z Hardware they can use whilst running
OS/390 2.5, but I am struggling to find any info out there at the moment.
