Issues related to workstation replacements for the Star4, and the readiness of ISCS workstation providers to supply equipment and software are best addressed by those providers. A listing of "known" workstation suppliers is available on the ISCS web page at www.nws.noaa.gov/iscs/workstationvendors.htm. All other workstation issues may be directed to the NOAA/NWS International Activities office.
