I do not recall Multi-core cpus being part of the initial z/arch
disclosure in 1979 when I was at that special meeting in POK for
CA. The ideas of the G3 chipset was announced about 2001 at
another disclosure meeting I went to in NY (forgot the name of
the town, it was not POK) given by Bob Rogers. S/390 v2.10 and
z/OS 1.1 were discussed and Bob said the two were so close to
each other he would have had to look at the CVT prefix to know
which OS was running on that machine.
Wasn't it the z14s that initially had "dual" core processing for
the zIIPs and IFLs? Eventually the zAAPs became zIIPs....
So many changes, that I just can't remember all of them.

AFAIK, IBM z is not a new architecture. Intel, Sun & HP invented multi-core CPU
chips. Intel invented PCI and PCIe. What is the new architecture that IBM z
introduced?
How long will it take to need > 64bit addressing?
64 bit data adressing already exists. As for programs, does anyone think they
can write a 4TB ( 64 bit ) program?
