    DECsystem 1090, KL-10D at about 1,900 pounds, ~600 pounds per
256 k-words of mainstore, and about 2.4 pounds per megaword of
disk space.  All of this good for a reasonable maximum of 1.2 MIPS
assuming one can stay within the cache; < 1 MIPS if not (1 uS memory
cycle) -- but, it does things 36 bits at a time, respects niceties
like halfwords, and has programmer-specified byte sizes.

    The CPU is good for about 22 kW of 3-phase power (most being
radiated as waste heat from the linear power supplies), each memory
box about 2 kW (it's core, after all), and the disks about 3 kW
(much more at startup).

    The all-up configuration occupies almost 400 square feet of
space.  (Note: all the comms gear and ancillary processors are
not included in the above numbers.)

    Let's just say that this thing is not "Energy Star" compliant.

    Why bother even counting them?  Even Beowulf clusters can't compete
with real "heavy metal".
