    I very much doubt it, most of the original A and B models were pulled in
    the late 80's for taking up too much floor space. A few D models and the
    triple density K models hung on until the mid 90's, but, by that time,
    they were so unreliable that they were replaced by modern units based on
    commodity drives.

    The 3380 was an obsolete heap of brown smelly stuff the day it was
    released, it had 14" platters mounted like a sawmill driven by a 1 horse
    motor through a flat rubber belt. A single HDA (head disk assembly) had
    2 sets of heads in the one plastic box along with the platters. There
    were 2 such units in one cab sharing one blower system which pumped
    large quantities of air through an absolute filter to the HDAs. This
    meant that, if you had to replace an HDA, you had to take 4 drives
    offline and lost the data on 2 of them. Changing an HDA was a 1 to 2
    hour job, more if it was a bad head crash, and the air system was
    contaminated. Meanwhile, the Japanese were producing compatible machines
    with 4 sealed drives, much more reliable, and the HDA could be changed
    in a matter of minutes if needed and only affected one drive.

    At one large site in Sydney, we replaced over 100 3380s with 2 EMC boxes
    in the mid 90s changing 2 very large rooms from hot crowded noisy places
    to large empty cool quiet places.

    I suspect that a few years of working on the danm things has done my
    hearing no good at all. In my experience, IBM has never produced a good
    state of the art storage system, as they say, Inferior But Marketable.
