Ivan Finch's Guisdap 2 at RAL
Ivan Finch of RAL reports that his version is still rough and may not work on Suns without some work. But, for hardy souls, a copy should be available via ftp from the RAL ftp server.
Older versions of Guisdap 2
Like Ivan's version, earlier versions probably won't work without some, or a lot of, work. They are available from the EISCAT download page for older versions of Guisdap 2.
