Basically, it was using up to 512 IIRC, custom chips, designed by Hsu, and made in conjunction with DARPMA (sp?), which is a Dept. of Defense agency tasked with advanced research. The total bill for all the work of Hsu's team, lots of other hardware, GM consultants, etc., was paid by IBM, for whom Hsu and his team worked at that time. It worked with an IBM computer for disk accesses, etc., so I'm sure it used IBM's flavor of Unix/Linux. The custom chips Hsu designed are not available to purchase, and would cost a fortune to re-create. It's rating today depends on who you talk to. You have to give it credit for beating, Kasparov, and it's search speed was truly incredible. On the down-side, being past history, it didn't have all the refinements in it's search or eval that the best programs use today; and Kaspy was not at his best for the re-match, which he lost. Because it was so quickly disassembled by IBM, and since Hsu is no longer working for IBM, no testing could be done to more definitively determine it's true strength versus today's or yesterday's programs, unfortunately. Looking at a few test set solutions, or games where Deep Blue played with just a few of it's many processors, in an effort to determine DB2's real strength, is naieve at best, IMO. dave
