Oh, and I suppose DEC hardware is all of exemplary quality?
You'd have to look hard, in my opinion, to find a piece of PC hardware
less reliable than the RA80! And certainly DEC committed plenty of
other sins of similar magnitude, even in the design and manufacture
of its very highest-end VAX hardware (e.g. the 9000 series, where the
CPU module design almost guaranteed overheating).
Sure, there's crummy PC hardware out there. Always has been, always
will be. But it's not realistic to pretend that our beloved VAXen
were paragons of reliability; in my experience, they were balky,
temperamental beasts that surely had their good points, but that
did not clearly outshine _quality_ PC hardware (certainly not of
today; probably not even that of five years ago) in reliability over
time.
