On closer inspection, the VAX 11/750 board that I have
marked "Property
of DEC, Not For Sale" is an M0006 - a Remote Diagnosis board. What can
you people tell me about it?
This was used by DEC to dial in to the
computer over a telephone line and
manage it as though someone were
typing at the console. It used an
unpublished protocol between the
kit at DEC's end ad the box at your
end.
Technically the box still belongs to
DEC ... or maybe COMPAQ ...
or soon HP.
The support engineer at DEC's end
could do whatever he liked to your machine,
but everyhting he did was recorded
by the support centre's systems.
