Hi, Earle.  It has been a long time since we have chatted.

I am afraid that after the datastream change for to use of PNG
compression for the imagery in the Unidata-Wisconsin broadcast, the
OS/2 box will be completely obsolete.  It would not be that big of a
chore to convert a PC over to something link Linux, FreeBSD, or Solaris
x86 and run your data ingestion/decoding/map generation on it.  The
project is most certainly easier than trying to figure out what to
modify on the OS/2 machine to keep it going.

I believe that there are ways of specifying what you request (Don is the
expert on this, but he is not in today), but the conversion of the
image compression scheme will nullify that shortly.

There are so many things being added to the datastreams, that it is hard
for really active sites to keep on top of things.  In your case, it would
seem to be almost impossible.

Again, the image stuff will be dying within a month or so.  Is the conversion
of a PC to a Unix OS out of the question?
