Since they drop the register addressing with PSW relative addressing
they execute faster. Does somebody have a list of S/370 instructions
with possible XA/ESA/Z replacements that can directly replaced?

Mike,
IMHO you talk about EAV in DS8000, but not about EAV.
EAV Volume (*) can be up to ~1TB big, but chunk size of 1113 cylinders
is for DS8000 family, AFAIK.
Space above 65520 cyl. is called EAS and from z/OS point of view the
smallest chunk is 21 cylinders.
So, you can allocate 1 track
Volumes have gotten bigger. The first 64K Cylinders (Mod 54) remain
the same, but EAV space past that can be added in 1113 cylinder chunks
to a multipile of 1113 cylinders. 250GB first step then 1000GB (or
so).

Steve,
Nothing changed since 2001.
We still use punched cards and reel tapes.
We love our 24-bit addressing and avoid 31-bit or 64-bit.
OK, there were some changes:
We migrated our memory from core to TTL.
Our Bus channels rusted away, so we moved to fiber optic.
Some of us started using
