The sad fact is that there is no where
near enough of us to soak up all the old mainframe gear out
there, and there is no way I could think to take all the equipment
that has to go away from business operations and try to offer
an alternative, so that is just the fact of life.
I do not think it is sad. The scrappers do play an important role in
the world, so if a large computer gets scrapped, it is actually a good
thing. They do a good job recycling the materials, and way down the
line we see this at the checkout line in the supermarket. About the
only time I would get sad is when the machine getting scrapped is
relatively important historically and rare.
If a 3420 gets scrapped - big deal. Same with 99.9 percent of the
machines that are coming out of service - DECs, Suns, IBMs, DGs, HPs,
etc.. Even if a PDP-11 gets scrapped - big deal. Except for a few
models, there are oodles of the things in collectors hands.
There are not many functional 3420s, and these are
pretty sad.
3420s were always a bit demanding - and this gets magnified when their
service life is examined. Most 3420s were running all day, every day,
for many years. They also lasted far longer than IBM ever envisioned -
30 plus years. The drives we see on minicomputers never got the
workout that 3420s received over thier lifetimes - not even close.
I have drifted off my topic here, but the bottom line
is
these were nice for parts as the seller said, but they were
no prize. I would not cry a lot once one of these or the
DASD got this damaged to see it get ground up, as parts
from these would do more harm than good in most cases
DASDs are a bit different - they are far more rare. The DASDs (hard
disk in IBMspeak) available in the 1970s (3330, 3340) are extremely
rare, and even those in the 80s are nearly as rare (3370, 3380).
