Why do MRV11-D's crap out? - test-drb@ccmp.vtda.org

I get requests for MRV11-D's regularly, like once a week.
Had a bunch and sold them.
Still have several in the field and have never seen one fail.

Are these things going bad?
Can't believe people are building new systems with them.
There's nothing much on them, just 2 boot ROM's and a simple QBUS interface.
The set of MXV11-B2 boot ROMs I have are 2764A's.
Do these die after awhile?
Just sitting here scratching my head.

Hi Ed
 Most EPROMs are rated for 10 years. That doesn't mean that
every one will last that long. Also, many of these types
of systems were all made with EPROMs from the same lot.
If there was a long term issue, they'd all fail.
