I remember the article on fluid computers in SciAm.  Also, I wrote a piece
for Scientific American entitled "The History of Census Tabulation" in the
Feb, 1989 edition, and still have a few offprints of the article.  If
anybody wants a copy, send your address directly to me at
KReid-Green@ets.org and I will mail you one--offer subject to availability.

See ANALYTICAL ENGINE 3.1 (Nov. '95) for more on this.  Our best information
is that CM's SDS 940 was scrapped in 1988, ah, sigh.  As the custodians of
the last (?) remaining SDS 930, we would dearly love to acquire the rackful
that made a 930 into a 940; but we have scant hope, it was a scarce piece at
best.

That 940 was donated to Resource One by Transamerica Leasing after it
finished a stint at SRI, where it had been the control computer for Shakey
the Robot.  Lee says that Shakey was "shaky" because the 940's DMA channel
was wired to the wrong voltage, and when Resource One got it they diagnosed
and rewired it.
