If so, it's not the only one.  A very good DEC Field Service person
I once knew had the theory that DEC diagnostics were designed to
convince the customer that his newly-delivered equipment was working
just fine so that he would sign off on it.  This person was only
partly jesting..

The other fun thing is knowing which "spurious" reported problems
(due to bugs in the diagnostics themselves) can be safely ignored.

Not to pick on DEC; I've seen this elsewhere too.

Heard at the Usenix conference (though it's apparently an old joke):

DEC diagnostics would run on a beached whale.
