   Yup, this happens a lot.  DEC has a patch out for this one.  When this
was discovered a few years back, DEC was giving out free replacement cable
harnesses.  They still might do so.  I encourage anyone who has the old-style
harnesses to replace them.  It is possible to have a cabinet fire in machines
with the old harness which are not properly cleaned, and I can assure you
that it's not a pretty sight.
