Hi John- That is a strong motion instrument and not much (any) value...
Try these 3 sites as I have bought systems from all 3 for schools and
they are quite good and very reliable...Jim
PS- write me off line sometime and we can talk geophysics...

Dave Saum in VA $200 seismograph

A real sophisticated system is found at  Larry Cochrane’s site in CA for
~$500:

Hello,

I am thinking of trying to buid a seisomgraph for my son's school.  I
have quite a bit of experience in shallow exploration geophysic's, mostly
electrical and electromagnetic, but none in seismology.  I ahve searched
the internet and found quite a few resources. 

 I have also noticed a seismograph (or strong motion accelerameter) on
sale at e-bay, with an opening bid of $75.  It is apparently an old unit
that was surplused from NOAA.  It is made by Teledyne Geotech and uses a
film recorder. The seller admits to knwing nothing about it.  Does anyone
know anything about these units.  Would it be difficult to convert to
recording on a computer? 

Thanks
