Sunset Dates for VGA
 and WIDE WORD Workstations

16 May 1997

Sunset dates for the McIDAS-OS2 VGA and WIDE WORD Workstation (WWW) configurations have been selected. The VGA configuration will be sunset on 1 October 1997, and the WWW configuration will be sunset 1 April 1998. This means that SSEC will no longer provide software or hardware support for those configurations after those dates.

The VGA is being sunset because the Presentation Manager (PM) display represents a significant increase in usability over the VGA. The WWW is being sunset because its architecture prevents using current PC hardware and software technology. For example, the WWW is limited to no more than 10 MB of PC RAM due to a memory address conflict with the hardware. Recent engineering tests at SSEC confirmed that it would require a redesign of the WWW to accommodate more than 10 MB of PC RAM.

The table below lists the support schedule for McIDAS-OS2 configurations through the May 1998 upgrade.
