Well, I can't speak for _all_ Alpha machines (because I haven't checked
on them all) ... but for the DEC 3000 that I have on my desk here,
there is a good-sized manual that tells you a _lot_ of info about the
hardware; it might not be enough to have you write your own OS for it,
but it's definately in the right direction.  I dunno if this is available
for all DEC machines, though.
