Dear List, A demonstration of JMACS is to be found at http://www.lafros.com/demos.html. Clicking on the 'application' or 'applet' link launches a user interface. The target system is an 'EISCAT Svalbard Radar' simulator, currently running a 'Cp3' experiment. Regards, Rob -- http://www.lafros.com +44 (0)1922 644 223
