Two 750's would not be as fast (well, if you add the MIPS they are a little faster) but you would have the overhead of running UNIX kernel in each processor. The I/O is slower probably in any case. I'm all for redundancy (so how about a 782?) but it would be nice to have a bigger machine so that everything was centralized rather than distributed. Mind you, I have nothing about distributed computing, but if you are talking about colocating the two 750's, I can't really see the point in it. I don't know why your people think the the technology in the 750 is any more modern than in the 780. It's just different in strange ways (and slower). DEC continually updates both processors with regard to technology. The memory density keeps increasing, for example. I have no indication that DEC will phase out the 780 until they come up with something as fast or faster. DEC is still pushing 780's and 782's all over the place. In the past, when DEC wanted to get rid of a product, they never had any great reservatins about dropping it from the literature and going out and telling prospective buyers that you really needed something else. -Ron
