I think the biggest benefit of the z9 is that the operating system is
supported. I believe next year z/OS 1.4 & 1.5 will go off support. Having
said that, the company I worked for last often ran unsupported software, and
to no real harm. We ran VM rel 5.1 until some time in 1999. I think that
was out of support for several years by the time we finally shut down VM.
We ran z/OS 1.2 until last month, which was over a year unsupported. We
have never had a problem that was made worse by not having support. Of
course, now P&H doesn't run a mainframe anymore.

This is not a flame - please - all these 64 bit supporters. Can you please
name a single access method which can do direct asynchromous or
synchronous
I/O to a 64 bit address space directly from a device using device
independent code. Something similar to DIV. A pointer to a sample code
will be great. I hope I am not asking too much?
