[alt.folklore.computers] Pneumatic computers

crichmon@digi.lonestar.org (Charles Richmond) (05/25/91)

Fifteen or so years ago I heard that in the '60's there were
computers constructed that ran from air pressure.  No electronics,
just air pressure.  These were constructed to fly through the
high-radiation van Alyn (sp?) belt that surrounds the earth.
Electronic computers were driven mad by the radiation, so the
pneumatic computers (although much slower) were used.

Does anybody know about this?  Are any such computers in
existence today?  (Hey, even if you only HEARD about it, that
would indicate that I did not dream it . . .)

I would like to learn about the construction and technology
involved with these pneumatic machines.

Yes, pneumatic computers are still around and under development by military
contractors.  One model can even be operated by blowing into it (i.e., the
human lung is the backup compressor).  They're slow due to mechanical
moving parts, but miniturization should help.

As important as the ability to function under radiation is
the ability to survive the electromagnetic pulse from a nuclear explosion,
which will render conventional computers inoperable.

P.S.  It's "Van Allen" as in "James Alfred Van Allen," who would be around
77 if he's still alive.
