OK, this is what was confusing me.  The boot prom said KA41-A, or something
like that, and was was not the VAX410, or so I thought.  A note to that effect
on the comment line next to the VAX410 line would help.  I looked about
for KA41, and the closest hunch was VAX410.  AS it turned out, that was
the correct one, anyway.
