They can be a big help if you are trying to interpret a crash dump of
the version you have AND you are familiar with VMS Internals. But, VMS
doesn't crash all that often, and the crash dump weenies in Colorado are
a hell of lot better at it than I am. (I saw, at most, two crash dumps
per year and the dump weenies do three or four per day!)

I learned VMS inside out reading crash dumps on systems with lots of
custom hardware attached. Trying to extract what I could about
hardware failures means getting to know the software, especially the
I/O subsystem. Oh, yes, sometimes those custom device drivers
were at fault.

And then there were the patches and user written system services we
maintained over VMS 2, 3, and 4 to allow us to do things VMS didn't
believe in.

Lots of fun when a faulty backplane in an 11/780 would occaisionally
read a user's EDT buffer when the CPU wanted a kernel page. You'ld
be surprised how many ASCII strings look like an illegal CHMK (not an
error the kernel will tollerate).

But it was all useful when I got that somewhat obscene trophy from
Bruce Ellis at his 1989 VMS trivia contest.
