[cctalk] Re: mainframe vs mini

That picture serves to remind us of the packaging and cooling genius that went into the CDC 6000 series machines, which could fairly be called the first supercomputers. Logic like that and more, but in a much smaller package so it can run faster. I suppose it didn't hurd that timing margins were shrunk down to microscopic values (and, if you try to analyze the design, sometimes they become negative, but somehow the machine worked anyway). They added a bunch of amazing magic to the core memory as well.
