When you say "a small-ish drive", what counts as "small" for VMS? Or
rather, what sort of drive should I be looking for to /not/ have to
muck around when installing it?
My hope is to get the machine booting into DECwindows. I don't plan to
use it as a server, more as sort of glorified X-terminal if anything.
