3B15 future

[John S. Lundberg]

We currently are running some Informix applications on an AT&T 3B15.  My
understanding is that this is a machine no longer being marketed by
AT&T.  I wonder if anyone could provide an informed guess of how much
longer 3B15s will be maintainable, i.e., how much longer AT&T will be
willing to write service contracts.  I have been told that there are
'practically none' of these machines outside of the BOCs.  Is this true?
