    Dear Mark,<br>
    <br>
    We will be interested in acquiring RefTek 72A-06/6 data acquisition
    <br>
    systems to be used as stand-alone deployments in special projects<br>
    including aftershock surveys in the northeast. <br>
    <br>
    On our experience, old Reftek DASs had major technical <br>
    problem stemming from SCSI disk drive failure, this accounted<br>
    more than 90% of the failure.   Recently, Patrick Bastien at <br>
    Lamont was able to replace those SCSI drive with low-power<br>
    consuming SD memory card (secure digital memory card used in <br>
    digital camera and cell phones).   Hence, we were able to<br>
    eliminate nearly all problem with the RefTek DAS.  So,<br>
    we can use the RefTek DASs for the next 5-10 years, I guess.<br>
    <br>
    Please let me know, how we can obtain some or all of those<br>
    surplus RefTek DASs.<br>
    <br>
    In case, if others wish to use the old RefTek DAS with the<br>
    modified 72A-05 (Reftek external disk drive), that will have<br>
    SD memory card, please let us know.  We can help to<br>
    make modification at reasonable costs ca. ~$200-300 per unit<br>
    for 8 or 16 Gbyte SD drive.<br>
    <br>
    We will be also interested in receiving Teledyne Geotech 1 Hz S13s<br>
    sensors.  We have been upgrading old analog legacy stations with<br>
    HS-10 short-period sensors that are very old (early ~1970s).<br>
    So, we can use as many S13s we can receive.  These are <br>
    ANSS stations in urban area with high risk. <br>
    <br>
    Regards<br>
    Won-Young<br>
