Check the 'timing'. If they had played a tournament with the real DB-1 or DB-2 hardware, it would have been within a couple of weeks of the event. For the last event they were seriously giving thought to either using the 1996 hardware or postponing, because the FAB shop screwed up badly several times (not design problems, but mis-communication inside the fab shop. IE Hsu wanted a 40-pin package. He got something bigger. He wanted interlaced data lines across the chip to save space. They didn't notice this. And even after all of that they had some ugly problems to solve in a period of a week or so. IE when you have 32 'wires' running in parallel, at high clock frequencies, with very close spacing, 'crosstalk' is a problem. They had to solve a bunch of problems with software kludges. And they were barely ready to play Kasparov at match time, much less ready to do demos months in advance. I was surprised how closely they cut it. I thought only us academic types did that kind of stuff (IE Cray Blitz became parallel in the two weeks immediately prior to the 1983 WCCC event we won... When I left for New York (driving, about 24 hours non-stop) the thing wasn't working due to a compiler problem. Harry was in Minneapolis working with Cray as we drove. That was close. DB had the same sort of problems, which was surprising in a way. But probably typical overall. :)
