The IRIS AmaSeis program is for use with the AS-1 seismometer.
Fetch Version 3.2 Level 2012.07.06 here: AmaSeisSetup.exe.
If you have installed an earlier version, or you want to use level 2012.07.06 (see below) all you need fetch and extract is the executable which is in the self-extracting file: AmaSeisUpgrade.exe.
A set of auxiliary programs are available for uploading and downloading real-time data: AmaSeisAuxSetup.exe. (Updated April 17, 2009)
Also, added "Recently used seismogram files" to the Files menu item so that you can easily select a previous file. This only works for SAC files.
