3390's or mainframes?
3390s.
The 3390's are a bit outdated now that the
RAMAC-4
SHARK DASD controllers are out. These are RAMAC-2 controllers. Still
useful though. A lot of places still want them. The only problem is that
each of these controllers can deal with racks and racks full of DASD, so
you only need one or two.
That seems to be the concensus. Those that need have plenty, and those
that don't need, also have plenty.
