Philip,
Thanks for the information on a seismic detector.  I found a .zip file
in the magazine's archive section 
( ftp://ftp.gernsback.com/pub/EN/seismic.zip ) which I think may
be the information on this system.  It is a triggered system that
one can set up via com port connection to a computer, then remove
from the computer and set up in the field.  Later the system is
returned to the computer for downloading the triggered events into
the computer, again via the com port.

This may be an interesting device for looking at local earthquakes,
but not teleseisms.

I believe the author is Ron Newton of Carson City, NV.( sjnewt@....... ).
Maybe he will join the PSN discussion group.

I am only one, But still I am one.
I cannot do everything, and because I cannot 
do everything, I will not refuse 
to do the something that I can do.
