That's one interpretation.  I'd take the other approach... that perhaps the
micro programs are a bit overrated...  and then there is computer vs computer,
where such a large speed differential is very important...

But DB junior is not better than DB.  DB junior was just a small piece of DB,
using 16 of the chess processors rather than 480, but everything else was
the same.  And all of this is "deep blue" hardware, _not_ the newer chips for
DB-2 that beat Kasparov...

It is stronger still...
