The 'old' computer was an ES/9021-RX2.5 years old.

The replacement was a 9672-R64 (circa 199?).
It's still on the floor (I no longer am) as a z/900 (unsupported).
I haven't been there for over four years, and it was around
The only thing that truly exists is the serial number.
Sounds like the 300 year old ax. The handle was replaced 5 times,
and the head 3 times, but it was the same ax.
Likewise, there are some DC-3s flying around whose only "original
equipment" are their shadows.
That is the only kind of computer that should have a 10 year life
span. But even it shouldn't have a 25 year life span without having
its IS functions redesigned.
One could probably fit a z9's "innards" into a S/360 box, if one were so
inclined....
