Doesn't really matter. If you want to use the name "deep blue using deep thought hardware" then that is why they called it (originally) deep blue prototype. The first DB did not exist until shortly before the first Kasparov match in 1996. The second DB did not exist until shortly before the second Kasparov match in 1997. Maybe we could use the names DB0, DB1 and DB2 to be clearer. But no matter, Fritz did _not_ play the machine that played Kasparov in 1996. >> >> >> >> >>> >>>Deep blue has nothing to do with the hardware but with the software of February >>>1993. >>>The assumption that Deep blue is about hardware of 1996 is wrong by definition >>>of IBM. >>> >>>Uri >> >> >>Not at all.

No... DB was the name IBM wanted to use for their new chess machine. DB was most definitely hardware _and_ software. They are "joined at the hip" so to speak. > >Junior with a 386 machine and with p700 machine is the same name inspite of the >different hardware. > >Uri So we don't have a junior 5, a junior 6, a junior 7, a crafty 17.x, a genius 3,4,5,6, etc??? They each denote a specific version of the program, and are usually qualified by the hardware they run on. Nobody says "Junior beat X" It is always "Junior on my PIII/800 beat X" because the program and hardware both contribute. In the case of Deep Blue, the hardware contribution is much larger since it _is_ deep blue's "heart".
