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...
