It's kind of funny to consider that modern desktop and server CPUs can have more Level-1 cache than that.
And they ran that system on a machine with 144kB of RAM, where desktop CPUs have had more Level-2 cache than that for years now.
And by now, as somebody else kindly points out, high end server CPUs approach Level 3 caches as big as the hard drive their system ran on... (I think zSeries CPUs have level 3 or level 4 caches in the 128MB range, so their caches actually are bigger than that.)
