Jerry,

 From what I can tell, the HS-3 acts as if it has an internal A/D, so no 
amplifiers or external electronics are required.  Its data feeds directly 
to the computer.  The problem is having data acquisition software like 
WinSDR work with it.  Rockwave appear to have written their own driver 
program to work with AmaSeis.  The biggest problem making such software may 
not be the reading of the data, but would be related to providing the 
instrument-unique commands to send to it to set it up and make it work.

Although it is true that they can use feedback to compensate for static 
ground tilt, it is also likely that it will respond to the rate of change 
of tilt, which may be almost as bad.

Nice looking instrument.
